•
This becomes velocity command input (analogue)
• You can set-up the relationship between the command
voltage level and the motor speed, with Pr50 (Velocity
Command Input Gain) .
• Use Pr51 to inverse the polarity of the command input.
< At torque control >*
•
This becomes torque command input (analogue)
• You can set-up the relationship between the command
voltage level and the motor torque, with Pr5C (Torque
Command Input Gain) .
• Use Pr5D to inverse the polarity of input signals.
• Use Pr56 (4th Speed Set-up) to adjust the speed limit in
torque control.
< Note >
SPR/TRQR are invalid in position control mode.
< At velocity and position control >
•
You can limit the motor torque in the CCW direction by
entering positive voltage (0 to +10V) to CCWTL.
• You can limit the motor torque in the CW direction by enter-
ing negative voltage (-10 to 0V) to CWTL.
• The torque limit value is proportional to the volt-
age with a factor of 100%/3V.
•
CCWTL and CWTL are valid when Pr03 (Torque Limit Input In-
hibit) = 0. They are invalid when Pr03 = 1.
< At torque control >*
• Both of CCWTL and CWTL are invalid.
• Use the 4th. speed set-up(Pr56) to limit the
speed.

* When the torque control mode is selected at the velocity/torque switching mode (Pr02 = 5), the
No.16 pin (CCWTL/TRQR) becomes the torque command input (analogue). You can set-up
the relationship between the command voltage level and the motor torque with Pr5C (Torque
Command Input Gain).
