-|Transparent setting guide|-
RES: Resolution setting switch
-Set the resolution of driver.
-The number of pulses per 1 rotation by resolution is each 500, 1000, 1600, 2000, 3200, 3600, 5000, 6400, 7200, 10000.
-Modified setting values are not applied in the running status, and the values will be applied after motor stopped.

GAIN: Motor gain setting switch
-Depending on GS H/L switch setting, the motor GAIN sets High or Low.
-Motor GAIN is selectable from 32 GAIN.
- The larger gain is, the more improved transient response becomes and the less error occurs.
※
At the lowest system load status, raise the gain value until motor vibrates and set to 1 to 2 level lower.
S.F: Speed Filter / Limit setting switch
-Depending on TM switch setting, speed filter and speed limit function can be set.
● Speed Filter
-In standard mode, it sets the delay time between the command position and the motor position.
- It determines the responsiveness of the motor to the command and smoothly follows the speed even if the load changes or disturbance occurs.
● Speed Limit
-In torque mode, it sets the speed limit.
- When the rotation speed reaches the speed limit value, the torque control may become unstable. Set value greater than the speed to be limited.

After position command pulse has finished, if the gap between target position and real position is under In-Position setting value, positioning
completion pulse is output.
