Torque Reference Settings: H3-04, H3-05, H3-08, H3-09
D
Set the multi-function analog input terminal 42 (H3-05) or 39 (H3-09) to torque reference (a setting of
13). The torque reference value cannot be set with the Digital Operator.

Setting Function
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)
D
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.
