Application macros
Torque Control macro
This macro provides parameter settings for applications that require torque control of
the motor. Control can also be switched to speed control. To enable, set the value of
parameter 9902 to 8 (
TORQUE CTRL
).
Connection example:
Input signals Output signals Jumper setting
• Two analog references (AI1, 2)
• Start/stop and direction (DI1, 2)
• Speed/torque control (DI3)
• Constant speed selection (DI4)
• Ramp pair 1/2 selection (DI5)
• Run enable (DI6) • Analog output AO1: Speed
• Analog output AO2: Current
• Relay output 1: Ready
• Relay output 2: Running
• Relay output 3: Fault

Note 1.
• Reverses rotation direction in
speed control.
• Reverses torque direction in
torque control.
Start/stop: Activation starts the drive.
Forward/reverse: Activation reverses direction

Ramp pair selection: Activate to select 2nd acc/dec ramp pair
Run enable: Deactivation always stops the drive
(Fault => 25 connected to 26)
Note 2.
The sensor needs to be powered.
See the manufacturer’s instructions.
A connection example of a two-wire
sensor is shown on page 80 .
