This display indicates that the 120 VAC power supply to the motor

amplifier has been cycled (turned off and back on).

This display indicates that the enable signal to the motor amplifier

from the RCS-2 channel card is low or disabled. (This is normal

when the unit is in the Ready or Halted state.)

This display indicates that the motor amplifier has commanded the

motor to turn at a certain speed but was unable to maintain that

speed. This usually indicates a motor, pump, or magnetic coupling

that is bound up and not able to turn freely.

This indicates that the motor amplifer was commanded by the RCS-

2 channel card to turn faster than the motor is capable of turning.

This typically indicates that improper parameters have been pro-

grammed into the RCS-2. Verify parameters such as pump size,

calibration factor, maximum pump speed, and maximum flow.

This indicates that the motor amplifier is no longer receiving feed-

back from the resolver mounted inside of the motor enclosure.

Check the two cables running from the back of the motor to the bot-

tom of the motor amplifier panel and the cables inside of the motor

amplifier panel running from the motor amplifier to the bottom of the

panel.

This indicates that the voltage being supplied to the motor amplifier

is excessive. Check the AC power supply voltage to the motor am-

plifer panel.

This indicates that the motor amplifier has exceeded the allowable

current limit for the motor. This usually indicates a motor, pump, or

magnetic coupling that is bound up and not able to turn freely.

This indicates that the motor is running excessively hot. Look for

binding of the motor magnetic coupling, or pump.

This indicates that the driver circuitry in the motor amplifier has ex-

ceeded the allowable temperature for that circuitry. This could indi-

cate a failure in the motor amplifier itself, a failure in the motor, or a

bound motor, pump, or magnetic coupling.
