Application Specific Adjustments
These settings are factory preset to provide optimum performance in a wide variety of applications, and should
not be changed unless the user is specifically aware of the risks and consequences (contact factory for details).
Brake On Delay (Switch SW1)
This DIP switch controls the amount of time that the ABC Series brake waits prior to applying DC current to the
motor windings in order to allow the magnetic field to decay. The rate of decay varies with motor frame size, so
this
SHOULD NOT BE CHANGED
. Changing this setting could result in damage to the ABC Series
components and circuit protective devices. If your application requires a specific delay time, please contact the
factory for assistance.
Zero Speed Sensing Disable (Jumper X3)
If for some reason you need to disable the Zero Speed Sensing, remove this jumper. The ABC Series will then
continue braking for the entire Brake Time setting, even if the motor has already come to a complete stop.
Disconnecting the sensing lead to the "T3" terminal, will cause a "Wiring Error" fault, and therefore should not be
used as a means of disabling the Zero Speed Sense circuit.
50 Hz Operation (Power Board Jumper X1)
Remove this jumper on units ordered as 60 Hz, but required to operate at 50 Hz. Units ordered as 50 Hz will not
have this jumper, so it must be installed for testing on 60 Hz systems.
CAUTION!
Some adjustments and devices visible on the ABC Series boards are preset at the factory and should NOT
be field adjusted without specific instructions from factory authorized service personnel. These devices
include: P1 and P2 potentiometers, and push button PB1. Tampering or altering these devices may void
your warranty.
