Torque Control Parameter
The following parameter is used for torque control. Set the parameter
according to requirements of the servo system that is used.

Default Setting: 30 Speed/Torque
Control
This parameter sets the voltage range for torque reference input T-REF
(CN1-9) depending on the output range of the host controller or external
circuit.
The default setting is 30, so the rated torque output is equal to 3V
(30 × 0.1).
This reference voltage is set.

Pn002.1 Setting Description
0 Uses speed limit set by Pn407 (internal speed limit function).
1
Uses V-REF (Cn1-5 and -6) as external speed limit input and
sets speed limit by voltage, which are input to V-REF and
Pn300 (external speed limit function).

Default Setting: 10000 Speed/Torque
Control
This parameter sets a motor speed limit when torque control is selected.
It is used to prevent excessive equipment speed during torque control.
Since the speed limit detection signal /VLT functions the same in torque
control as the /CLT signal, see
5.1.3 Limiting Torque,
where the /CLT
signal is described.
