Control Adjustments
Channel 1 and Channel 2 Torque Adjustment: Provides adjustment of 0 to full rated voltage.

Channel 1 and Channel 2 function in an alternate mode. In the dual mode Channel 1
and Channel 2 function simultaneously. This mode will be employed in applications with
a clutch and a failsafe brake. The control is shipped with the jumper placed for the
single mode of operation. To change to dual mode, carefully remove the jumper and
reinsert it on the dual side of the terminal block.
Frequency Provides adjustment of 60 to 400 Hz. This adjustment is simply to reduce the
