4) Set the following user constants for torque control according to the servo system used.
TCRFGN
Cn-13 Torque Reference
Gain
This user constant is for speed/torque control
(SGDA-jjjS) only.
Sets the voltage range of torque reference input
T-REF (1CN-1) according to the output form of the
host controller or external circuit.
The factory setting is 30, so the rated torque is 3 V (30 x 0.1).
TCRLMT
Speed Limit for Torque
Cn-14
Control I
Sets a motor speed limit value in this constant
when torque control I is selected.
This user constant is used to prevent machine
overspeed during torque control.
For torque control I, set bits A and B of memory switch Cn-01.
VREFGN
Cn-03 Speed Reference
Gain
This user constant is for speed/torque control
(SGDA-jjjS) only.
Sets the voltage range of speed reference input V-
REF (1CN-3) according to the output form of the
host controller or external circuit.
The factory setting is 500 [rated speed (3,000 r/min)/6 V = 500].
