Shutdown input (pin 6, J1) is pulled low.
See Figure 2-5.
High DC bus voltage (pins 28, 32 or J1).
See Figure 2-5.
+12VDC input (pin 20, J1) is below +11VDC.
See Figure 2-5.
Active LED is de-energized,
even with ±12VDC applied to
pins 20 and 22 of J1.
Short circuit exists at motor connections (pin 26, 30 or J1)
See Figure 2-5.
Motor load fuse F1 is open
See Figure 2-5.
I limit + (pin 12, J1) and/or I limit – (pin 14, J1) contact
closed to signal common.
See Figure 2-5.
No DC bus voltage on +B, +B return (pins 28, 32 of J1)
See Figure 2-5.
Active LED is energized, but
no torque is present at motor
shaft.
Current limit pot turned full CW.
See Figure 2-5.
Tach feedback wires reversed (pin 18, 24 of J1)
See Figure 2-5.
Motor accelerated to full
speed when power was
applied.
Personality module removed
See Figure 2-6.
Motor has high pitch
(oscillation) sound when
power is applied.
Tach and or Gain pot turned too high.
See Figure 2-6.
Ripple current (peak to peak) in excess of 20% of continuous
return of motor, due to too high pre-amplifier gains.
See Figure 2-6.
Motor gets excessively hot
when running at minimum
load condition (reference
current monitor, pin 8 of J1).
Ripple current (peak to peak) in excess of 20% of continuous
return of motor, due to too low motor inductance.
See Figure 2-6.
