7. GENERAL GAIN ADJUSTMENT 7.2.3 Adjustment procedure by auto tuning Since auto tuning is made valid before shipment from the factory, simply running the servo motor automatically sets the optimum gains that match the machine. Merely changing the response level setting value as required completes the adjustment.
7. GENERAL GAIN ADJUSTMENT 7.2.4 Response level setting in auto tuning mode Set the response (The first digit of parameter No.2) of the whole servo system. As the response level setting is increased, the trackability and settling time for a command decreases, but a too high response level will generate vibration.

7. GENERAL GAIN ADJUSTMENT (c) Adjustment description 1) Position control gain 1 (parameter No. 6) This parameter determines the response level of the position control loop. Increasing position control gain 1 improves trackability to a position command but a too high value will make overshooting liable to occur at the time of settling.
7. GENERAL GAIN ADJUSTMENT 7.4 Interpolation mode The interpolation mode is used to match the position control gains of the axes when performing the interpolation operation of servo motors of two or more axes for an X-Y table or the like.

The communication cable for connection with the personal computer (MR- CPCATCBL3M) is available.
14. COMMUNICATION FUNCTIONS 14.2 Communication specifications 14.2.1 Communication overview This servo amplifier is designed to send a reply on receipt of an instruction. The device which gives this instruction (e.g. personal computer) is called a master station and the device which sends a reply in response to the instruction (servo amplifier) is called a slave station.
14. COMMUNICATION FUNCTIONS 14.2.2 Parameter setting When the RS-422/RS-232C communication function is used to operate the servo, set the communication specifications of the servo amplifier in the corresponding parameters. After setting the values of these parameters, they are made valid by switching power off once, then on again.
14. COMMUNICATION FUNCTIONS 14.3 Protocol POINT Whether station number setting will be made or not must be selected if the RS-232C communication function is used. Note that choosing "no station numbers" in parameter No. 53 will make the communication protocol free of station numbers as in the MR-J2-A servo amplifiers. Since up to 32 axes may be connected to the bus, add a station number or group to the command, data No., etc.

14. COMMUNICATION FUNCTIONS 14.5 Error codes Error codes are used in the following cases and an error code of single-code length is transmitted. On receipt of data from the master station, the slave station sends the error code corresponding to that data to the master station.
14. COMMUNICATION FUNCTIONS 14.7 Time-out operation The master station transmits EOT when the slave station does not start reply operation (STX is not received) 300[ms] after the master station has ended communication operation. 100[ms] after that, the master station retransmits the message. Time-out occurs if the slave station does not answer after the master station has performed the above operation three times.
14. COMMUNICATION FUNCTIONS 14.9 Initialization After the slave station is switched on, it cannot reply to communication until the internal initialization processing terminates. Hence, at power-on, ordinary communication should be started after: (1) 1s or more time has elapsed after the slave station is switched on; and (2) Making sure that normal communication can be made by reading the parameter or other data which does not pose any safety problems.

15. ABSOLUTE POSITION DETECTION SYSTEM 15.3 Battery installation procedure Before starting battery installation procedure, make sure that the charge lamp is off WARNING more than 10 minutes after power-off. Then, confirm that the voltage is safe in the tester or the like. Otherwise, you may get an electric shock. POINT The internal circuits of the servo amplifier may be damaged by static electricity.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.5 Signal explanation When the absolute position data is transferred, the signals of connector CN1 change as described in this section. They return to the previous status on completion of data transfer. The other signals are as described in Section 3.3.2.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.6 Startup procedure (1) Battery installation. Refer to Section 15.3 installation of absolute position backup battery. (2) Parameter setting Set "1 "in parameter No. 1 of the servo amplifier and switch power off, then on. (3) Resetting of absolute position erase alarm (AL.25) After connecting the encoder cable, the absolute position erase alarm (AL.25) occurs at first power-on.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7 Absolute position data transfer protocol POINT After switching on the ABS transfer mode (ABSM), turn on the servo-on signal (SON). When the ABS transfer mode is off, turning on the servo-on signal (SON) does not switch on the base circuit. 15.7.1 Data transfer procedure Each time the SON signal is turned ON (when the power is switched ON for example), the programmable controller reads the position data (present position) of the servo amplifier.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.2 Transfer method The sequence in which the base circuit is turned ON (servo-on) when it is in the OFF state due to the servo-on signal (SON) going OFF, an emergency stop, or alarm, is explained below. In the absolute position detection system, every time the servo-on (SON) signal is turned on, the ABS transfer mode (ABSM) signal should always be turned on to read the current position in the servo amplifier to the controller.
Page 282
15. ABSOLUTE POSITION DETECTION SYSTEM 1) The ready signal (RD) is turned ON when the ABS transfer mode signal (ABSM) is turned OFF after transmission of the ABS data. While the ready signal (RD) is ON, the ABS transfer mode signal (ABSM) input is not accepted. 2) Even if the servo-on (SON) signal is turned ON before the ABS transfer mode signal (ABSM) is turned ON, the base circuit is not turned ON until the ABS transfer mode signal (ABSM) is turned ON.

15. ABSOLUTE POSITION DETECTION SYSTEM (c) Checksum The check sum is the code which is used by the programmable controller to check for errors in the received ABS data. The 6-bit check sum is transmitted following the 32-bit ABS data. At the programmable controller, calculate the sum of the received ABS data using the ladder program and compare it with the check sum code sent from the servo.
Page 285
15. ABSOLUTE POSITION DETECTION SYSTEM (2) Transmission error (a) Time-out warning(AL.E5) In the ABS transfer mode, the time-out processing shown below is executed at the servo. If a time- out error occurs, an ABS time-out warning (AL.E5) is output. The ABS time-out warning (AL.E5) is cleared when the ABS transfer mode (ABSM) changes from OFF to ON.
Page 286
15. ABSOLUTE POSITION DETECTION SYSTEM 3) ABS transfer mode finish-time time-out check If the ABS transfer mode signal is not turned OFF within 5s after the last ready to send signal (19th signal for ABS data transmission) is turned ON, it is regarded as the transmission error and the ABS time-out warning (AL.E5) is output.
Page 287
15. ABSOLUTE POSITION DETECTION SYSTEM (3) At the time of alarm reset If an alarm occurs, turn OFF the servo-on (SON) signal by detecting the alarm output (ALM). If an alarm has occurred, the ABS transfer mode signal (ABSM) cannot be accepted. In the reset state, the ABS transfer mode signal (ABSM) can be input.
Page 288
15. ABSOLUTE POSITION DETECTION SYSTEM (4) At the time of emergency stop reset (a) If the power is switched ON in the emergency stop state The emergency stop state can be reset while the ABS data is being transferred. If the emergency stop state is reset while the ABS data is transmitted, the base circuit is turned ON 80[ms] after resetting.
Page 289
15. ABSOLUTE POSITION DETECTION SYSTEM (b) If emergency stop is activated during servo-on The ABS transfer mode signal (ABSM) is permissible while in the emergency stop state. In this case, the base circuit and the ready signal (RD) are turned ON after the emergency stop state is reset.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.3 Home position setting (1) Dog type home position return Preset a home position return creep speed at which the machine will not be given impact. On detection of a zero pulse, the home position setting signal (CR) is turned from off to on. At the same time, the servo amplifier clears the droop pulses, comes to a sudden stop, and stores the stop position into the non-volatile memory as the home position ABS data.
Page 291
15. ABSOLUTE POSITION DETECTION SYSTEM (2) Data set type home position return Move the machine to the position where the home position is to be set by performing manual operation such as jog operation to turn the motor shaft more than one revolution. When the home position setting signal (CR) is on for longer than 20ms, the stop position is stored into the non-volatile memory as the home position ABS data.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.4 Use of servo motor with electromagnetic brake The timing charts at power on/off and servo-on (SON) on/off are given below.

15. ABSOLUTE POSITION DETECTION SYSTEM 15.7.5 How to process the absolute position data at detection of stroke end The servo amplifier stops the acceptance of the command pulse when stroke end (LSP LSN) is detected, clears the droop pulses to 0 at the same time, and stops the servo motor rapidly. At this time, the programmable controller keeps outputting the command pulse.
15. ABSOLUTE POSITION DETECTION SYSTEM 15.8 Examples of use 15.8.1 MELSEC-A1S (A1SD71) (1) Instructions The absolute coordinate system (programmable controller coordinate system) of the A1SD71 (AD71) only covers the range in which the address increases (positive coordinate values) on moving away from the machine home position (the position reached in the home position return operation).
Page 295
15. ABSOLUTE POSITION DETECTION SYSTEM If the address of the machine home position is changed to any coordinate value other than "0", the programmable controller coordinate system will be as illustrated below. The power should be turned ON/OFF in the range in which the address increases on moving away from the home position.
