Direct Drive Motor Specifications and Instruction Manual
7 Setup
7.1 Setting the Initial Parameters for the Direct-drive Motor
The servo parameters must be set before the direct-drive motor can be started up. The servo parameters are input from
the NC. The input method differs according to the NC being used, so refer to each NC Instruction Manual.
When setting the initial setting parameters, perform the following settings.
<For direct-drive motor system>
(1) Set the standard parameters in the section "7.1.2 List of standard parameters for each direct-drive motor".
(2) "7.1.1 Setting of encoder related parameter"
CAUTION
Do not release the emergency stop even after setting the above initial parameters. The initial setup (refer to the section "7.2
Initial setup for the direct-drive motor system") is always required to enable the test operation for the direct-drive motor (Ex.
manual pulse feed, low-speed JOG feed).
7.1.1 Setting of Encoder Related Parameters
Set the encoder related parameters below depending on the encoder connected.

【#2219(PR)】 SV019 RNG1 Sub side encoder resolution
Set the number of pulses per revolution in one "kp" increments.
Note that the value must be input in increments of 10K pulses (the 1st digit of the setting value is
"0").
If any restriction is imposed due to the above condition, also set SV117 in one pulse increments.
【#2220(PR)】 SV020 RNG2 Main side encoder resolution
Set the same value as SV019.
【#2317(PR)】 SV117 RNG1ex Expansion sub side encoder resolution
To set the resolution of the motor side encoder in one pulse increments, set the number of pulses of
the encoder by 4-byte data in total to SV117 (high-order 16bit) and SV019 (low-order 16bit).
SV117= Quotient of the number of pulses divided by 65536 (If the quotient is 0, set SV117 to -1).
SV019= Remainder of the number of pulses divided by 65536
If the NC is C70 and SV019 is greater than 32767, enter the (negative) value obtained by subtracting
65536 from the above remainder in SV019.
【#2318(PR)】 SV118 RNG2ex Expansion main side encoder resolution
Set the same value as SV117.
