CHAPTER 7: MAINTENANCE, REPAIR, and WARRANTY
7.2.2 Under Voltage Fault:
When the +15VDC is below +12VDC, a level that would cause unreliable operation,
the Run LED will turn off, a Fault Output is generated, and the amplifier is inhibited. This
is not a latched condition: that is, if the problem is resolved the amplifier will resume
operation.
The following is a list of possible causes:
1. Main AC line voltage is too low.
2. Bad rectifier bridge.
3. Bad DC buss filter capacitor.
7.2.3 Motor Over Temp Fault:
When the motor temperature has reached a level that, if exceeded, would damage
the motor, the Run LED will turn off, the OVER TEMP LED will turn on and a Fault Output
is generated, and the amplifier is inhibited. Note: This is a latched condition.
The following is a list of possible causes:
1. The continuous motor current is too high.
2. Binding or stalling of motor shaft due to excessive mechanical overload.
3. Motor rating too small for the load.
7.2.4 High Speed Electronic Circuit Breaker (HS/ECB) Fault:
When the peak output of the amplifier exceeds 40A for 10 micro-seconds, the Run
LED will turn off, the HS/ECB LED will turn on and a Fault Output is generated, and the
amplifier is inhibited. Note: This is a latched condition.
The following is a list of possible causes:
1. Shorted motor leads.
2. Motor inductance too low.
3. Short from a motor lead to ground.
7.2.5 Low Speed Electronic Circuit Breaker (LS/ECB) Fault:
When the RMS output of the amplifier exceeds 5A for standard 60VAC, 10A for High
Power 60VAC, 3A for standard 120/240VAC or 6A for High Power 120/240VAC for 3
seconds, the Run LED will turn off, the LS/ECB LED will turn on and a Fault Output is
generated, and the amplifier is inhibited. Note: This is a latched condition.
The following is a list of possible causes:
1. Binding or stalling of motor shaft due to excessive mechanical overload.
2. Overload of amplifier output to motor.
3. Large reflected load inertia.
