  • Page 2: Safety Instructions

    Safety Instructions (Always read these instructions before using the equipment.) Do not attempt to install, operate, maintain or inspect the servo amplifier and servo motor until you have read through this Instruction Manual, Installation guide, Servo motor Instruction Manual and appended documents carefully and can use the equipment correctly.
  • Page 3 1. To prevent electric shock, note the following: WARNING Before wiring or inspection, turn off the power and wait for 15 minutes or more until the charge lamp turns off. Then, confirm that the voltage between P and N is safe with a voltage tester and others. Otherwise, an electric shock may occur.
  • Page 4 4. Additional instructions The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock, etc. (1) Transportation and installation CAUTION Transport the products correctly according to their masses. Stacking in excess of the specified number of products is not allowed. Do not carry the servo motor by the cables, shaft or encoder.
  • Page 5 CAUTION Do not install or operate the servo amplifier and servo motor which has been damaged or has any parts missing. Provide adequate protection to prevent screws and other conductive matter, oil and other combustible matter from entering the servo amplifier and servo motor. Do not drop or strike servo amplifier or servo motor.
  • Page 6 (3) Test run adjustment CAUTION Before operation, check the parameter settings. Improper settings may cause some machines to perform unexpected operation. The parameter settings must not be changed excessively. Operation will be insatiable. (4) Usage CAUTION Provide an external emergency stop circuit to ensure that operation can be stopped and power switched off immediately.
  • Page 7 (6) Maintenance, inspection and parts replacement CAUTION With age, the electrolytic capacitor of the servo amplifier will deteriorate. To prevent a secondary accident due to a fault, it is recommended to replace the electrolytic capacitor every 10 years when used in general environment.
  • Page 8 COMPLIANCE WITH EC DIRECTIVES 1. WHAT ARE EC DIRECTIVES? The EC directives were issued to standardize the regulations of the EU countries and ensure smooth distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January, 1997) of the EC directives require that products to be sold should meet their fundamental safety requirements and carry the CE marks (CE marking).
  • Page 9 (3) Environment Operate the servo amplifier at or above the contamination level 2 set forth in IEC60664-1. For this purpose, install the servo amplifier in a control box which is protected against water, oil, carbon, dust, dirt, etc. (IP54). (4) Power supply (a) Operate the servo amplifier 7kW or less to meet the requirements of the overvoltage category II set forth in IEC60664-1.
  • Page 10 (7) Auxiliary equipment and options (a) The no-fuse breaker and magnetic contactor used should be the EN or IEC standard-compliant products of the models described in section 13.2.2. (b) The sizes of the cables described in section 13.2.1 meet the following requirements. To meet the other requirements, follow Table 5 and Appendix C in EN60204-1.

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 servo-on (SON) is turned ON (when the power is switched ON for example), the programmable controller reads the position data (present position) of the servo amplifier.
  • Page 329: Transfer Method

    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 (SON) going OFF, an emergency stop (EMG), or alarm (ALM), is explained below. In the absolute position detection system, every time the servo-on (SON) is turned on, the ABS transfer mode (ABSM) should always be turned on to read the current position in the servo amplifier to the controller.
  • Page 330 15. ABSOLUTE POSITION DETECTION SYSTEM 1) The ready (RD) is turned ON when the ABS transfer mode (ABSM) is turned OFF after transmission of the ABS data. While the ready (RD) is ON, the ABS transfer mode (ABSM) input is not accepted. 2) Even if the servo-on (SON) is turned ON before the ABS transfer mode (ABSM) is turned ON, the base circuit is not turned ON until the ABS transfer mode (ABSM) is turned ON.

  • Page 332 15. ABSOLUTE POSITION DETECTION SYSTEM (c) Checksum The checksum is the code which is used by the programmable controller to check for errors in the received ABS data. The 6-bit checksum 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 checksum code sent from the servo.
  • Page 333 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 334 15. ABSOLUTE POSITION DETECTION SYSTEM 3) ABS transfer mode finish-time time-out check If the ABS transfer mode (ABSM) 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 335 15. ABSOLUTE POSITION DETECTION SYSTEM 5) Servo-on (SON) OFF, Reset (RES) ON, Emergency stop (EMG) OFF check during the ABS transfer When the ABS transfer mode is turned ON to start transferring and then the servo-on (SON) is turned OFF, the reset (RES) is turned ON, or the emergency stop (EMG) is turned ON before the 19th send data ready signal is turned ON, the ABS time-out warning (AL.E5) occurs, regarding it as a transfer error.
  • Page 336 15. ABSOLUTE POSITION DETECTION SYSTEM (b) Checksum error If the checksum error occurs, the programmable controller should retry transmission of the ABS data. Using the ladder check program of the programmable controller, turn OFF the ABS transfer mode (ABSM). After a lapse of 10ms or more, turn OFF the servo-on (SON) (OFF time should be longer than 20ms) and then turn it ON again.
  • Page 337 15. ABSOLUTE POSITION DETECTION SYSTEM (3) At the time of alarm reset If an alarm occurs, turn OFF the servo-on (SON) by detecting the alarm output (ALM). If an alarm has occurred, the ABS transfer mode (ABSM) cannot be accepted. In the reset state, the ABS transfer mode (ABSM) can be input.
