Set the proper signal level for the torque reference that you want to input.
D
The direction of the torque that is output is determined by the sign (polarity) of the signal that was input.
It is not determined by the direction of the run command (forward/reverse).
•
+Voltage (or current):
Forward torque reference (generally counterclockwise; axis side)
•
−
Voltage:
Reverse torque reference (generally clockwise; axis side)
Since the polarity of the voltage input determines the direction, only forward torque references can be
input when the “0 to +10 V” or “4 to 20 mA” signal level has been selected. If you want to input reverse
torque references, be sure to select the “0 to
±
10 V” signal level.
D
When supplying a voltage input to the frequency reference current input (terminal 14) (a setting of 0
or 1), be sure to disconnect jumper wire J1 on the control board. (See
Figure 7.11
.) If the jumper wire
isn’t disconnected, the input resistor will be destroyed.

Speed Limit Function Settings: d5-03, H3-01, d5-04, d5-05
D
This setting selects the speed limit function used when torque control is performed.
With torque control, the motor sometimes rotates at high speed with no load or a light load. The speed
limit function keeps the motor speed from exceeding the specified limit in these cases.
D
If the speed limit is exceeded during torque control operation, a suppressing torque (proportional to
the divergence from the speed limit) is added to the torque reference. (The suppressing torque is ap-
plied opposite to the motor rotation.)
D
There are two ways to set the motor speed limit: a constant setting or an analog input value.
