4d. Now slowly adjust the anti-residual
potentiometer “A” clockwise while
feeling the reaction on the brake.
When the optimum anti-residual output is
obtained, the brake will be very free to
rotate without much resistance. This is
best if done at core diameter.
Note: Using a meter across the brake “A”
terminals 5 and 6 as noted in 4c above,
the voltage observed should be
negative at this time.
4e. Once this point is found, do not adjust
this potentiometer further or the brake
can re-engage.
4f. If a second brake is used on Channel
“B”, then proceed to step 5 otherwise
this completes the anti-residual
adjustment for the “A” Channel.
Continue to step 6.
5. Adjust the anti-residual output for Channel
“B” as follows if a brake is used on this
output. If no brake is used, then disregard
this portion of the start-up. Proceed to step
6.
5a. Using a digital DC Voltmeter, connect the
positive lead to terminal 3 and the
negative lead to terminal 4 of the
MCS2000-DRV2 for Channel “B” input.
5b. Adjust the Tension controller being used
to give a 0 VDC reading on the Channel
“B” input.
This is anti-residual mode only.
5c. Using a small screwdriver, rotate the
anti-residual potentiometer “B” fully
counter-clockwise so the output voltage
to the brake is zero level. Voltage can be
measured to the Channel “B” brake on
terminals 7 and 8 of the MCS2000-DRV2.
Terminal 7 is positive, and terminal 8 is
negative. Note that the “GREEN” LED for
Channel “B” is flashing at this time.
5d. Now slowly adjust the anti-residual
potentiometer “B” clockwise while feeling
the reaction on the brake. When the
optimum anti-residual output is obtained,
the brake will be very free to rotate
without much resistance. This is best if
done at core diameter.

The Channel “A” is operating in the anti-residual
mode with the following indication.
Flashing “ON” 1.5 sec, “OFF” 0.5 sec
RED LED is “OFF”
- (Green)
The following LED indications will be present when anti-residual current is applied to the brake.
