5.2.9. Torque Limiting by Analog Voltage Reference
Torque limiting by analog voltage reference limits the torque by
assigning a torque analog voltage to the T-REF terminal (CN1-9 and
10). It cannot be used for torque control because the torque reference
input terminal T-REF is used as an input terminal.
The torque is limited at the forward run side when the P-CL signal turns
ON and at the reverse run side when the N-CL signal turns ON.
 Using Torque Limiting by Analog Voltage Reference
To use this function, set the following parameter to 3:
Parameter Signal Setting (rpm) Control Mode
Pn002.0
Speed Control Option
(T-REF Terminal
Allocation)
Default Setting: 0
Speed Control,
Position Control
This parameter can be used to enable torque limiting by analog voltage
reference.
Pn002.0 Setting T-REF Function
0 None.
1 T-REF terminal used for external torque limit input.
2 T-REF terminal used for torque feed-forward input.
3
T-REF terminal used for external torque limit input when P-CL
and N-CL are valid.
This function cannot be used with the torque feed-forward function
described in 5.2.8 Torque Feed-Forward Function.
