Signal Level Settings

D
Setting
0 0 to +10 V input (When H3-08 is being set, be sure to disconnect jumper wire J1.)
1 0 to ±10 V input (When H3-08 is being set, be sure to disconnect jumper wire J1.)
2 4 to 20 mA input (H3-08 only)
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.
D
It is not determined by the direction of the run command (forward/reverse).
+Voltage (or current):
•
−Voltage:
•
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.
When supplying a voltage input to the frequency reference current input (terminal 14) (a setting of 0
D
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

J
This setting selects the speed limit function used when torque control is performed.
D
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.
If the speed limit is exceeded during torque control operation, a suppressing torque (proportional to
D
the divergence from the speed limit) is added to the torque reference. (The suppressing torque is ap-
plied opposite to the motor rotation.)
There are two ways to set the motor speed limit: a constant setting or an analog input value.
