DR500 Operation and Technical Manual
Table 2-12. DS160 Series Troubleshooting Guide
Condition
Active LED is de-energized,
even with ±12VDC applied to
pins 20 and 22 of J1.
Active LED is energized, but
no torque is present at motor
shaft.
Motor accelerated to full
speed when power was
applied.
Motor has high pitch
(oscillation) sound when
power is applied.
Motor gets excessively hot
when running at minimum
load condition (reference
current monitor, pin 8 of J1).

Possible Cause
Shutdown input (pin 6, J1) is pulled low.
High DC bus voltage (pins 28, 32 or J1).
+12VDC input (pin 20, J1) is below +11VDC.
Short circuit exists at motor connections (pin 26, 30 or J1)
Motor load fuse F1 is open
I limit + (pin 12, J1) and/or I limit – (pin 14, J1) contact
closed to signal common.
No DC bus voltage on +B, +B return (pins 28, 32 of J1)
Current limit pot turned full CW.
Tach feedback wires reversed (pin 18, 24 of J1)
Personality module removed
Tach and or Gain pot turned too high.
Ripple current (peak to peak) in excess of 20% of continuous
return of motor, due to too high pre-amplifier gains.
Ripple current (peak to peak) in excess of 20% of continuous
return of motor, due to too low motor inductance.

Comment
--
--
Use any "slow blow" fuse (no greater than 10
amp for DS16020 and 15 amp for DS16030
current with no less than 250 Volt rating).
Fuse size: 3 AG
Used for pre-selection of gain parameters for
other motor combinations.
