5-8-5. Torque limit
5-8-5-1. Internal speed limit
Limit the speed of torque control by setting below parameters:
5-8-5-2. External speed limit
Limit the speed output of torque control mode by the analog voltage command input from
V-REF terminal.
distribution
speed limit input
The analog voltage has no polarity. The absolute value of the voltage is
reverse direction.
2. The parameter value is related to voltage command and P3-00 when it is used as speed limit value.
For example: P3-00=500 (voltage of rated speed is 5.0V), T-REF voltage command is 1.0V, the
speed limit is 20% of rated speed.
3. P0-08=1, the actual limit value is the smaller value among V-REF speed limit input and P4-07.

1 if the motor speed is up to speed limit value in torque control mode, it will output /VLT signal.
2 /VLT can be distributed to output terminal via parameter P5-33. Refer to chapter 5-12-3.
5-8-6. Torque command input dead area voltage
l speed limit in torque control mode
Note: the actual speed is max speed even this parameter speed is larger than the max speed.
2500:3000
3000:4000
09 is effective in all modes.
2. Default setting is different for each type. For example: max speed is 2000 for rated speed 1500
motor, max speed is 4000 for rated speed 3000 motor.
3. This parameter is related to E-008 and E-010. If motor speed is larger than max speed+200, servo
will show E-008 over-speed. If the pulse frequency converts to motor speed, the speed is larger than
max speed; but the actual motor speed is max speed. Then the pulse offset will accumulate, servo will
show E-010 alarm.
Torque command input dead area voltage
if the input torque command voltage is smaller than this parameter, the torqu
