5. PARAMETERS
Class No. Symbol
23 FFC Feed forward gain:
Used to set the fee forward gain.
When it is set to 100%, droop pulses will not be generated in
constant-speed operation. Note that sudden acceleration/deceleration
will increase overshoot.
When setting this parameter, always set auto tuning (parameter No.
2) to No
24 ZSP Zero speed:
Used to set the output range of the zero speed signal (ZSP).
25 VCM Analog speed command maximum speed:
Used to set the speed at the maximum input voltage (10V) of the
analog speed command (VC).
Set 0 to select the rated speed.
Analog speed limit maximum speed:
Used to set the speed at the maximum input voltage (10V) of the
analog speed limit (VLA).
Set 0 to select the rated speed.
26 TLC Analog torque command maximum output:
Used to set the output torque at the analog torque command voltage
(TC = 8V) of +8V on the assumption that the maximum torque is
100[%]. For example, set 50 to output (maximum torque
the TC of +8V.
27 *ENR Encoder output pulses:
Used to set the number of output pulses per encoder revolution
output by the servo amplifier.
28 TL1 Internal torque limit 1:
Set this parameter to limit servo motor-generated torque on the
assumption that the maximum torque is 100[%]. When 0 is set,
torque is not produced.
Internal torque limit 1:
Set this parameter to limit servo motor-generated torque on the
assumption that the maximum torque is 100[%].
When 0 is set, torque is not produced.
