Rated torque
Two speed limit functions during torque control are available by the user constant setting as
shown below.
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 input to V-REF and Pn300. (external speed limit
function)

Speed/Torque
Control
The user constant 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 asthe /CLT sig-
nal, see 5.1.3
Limiting Torque,
where the /CLT signal is described.

The maximum speed of the Servomotor will be used if Pn407 is set to a value higher than the
maximum speed of the Servomotor.
External speed limit function
This is function uses V-REF (CN1-5) as external speed limit input and sets input voltage range
by Pn300. Set the range according to host computer and the output state of external circuit.
