11
MDU SERIAL
TIMEOUT
• Motor drive has lost communication
with the KCM CPU and then turns off
all digital outputs and shuts of drive
power.
12 MDU THERMAL
OVL
• Drive temperature has been
exceeded > 75 deg C. Drive stops.
13 MDU SPEED
DEV
• No speed feedback signal is present
when motor is asked to run.
• Speed deviation from target >
5
rpm
• Wrong motor voltage programmed.
14
MOTOR
OVERLOAD
• Motor current limit is exceeded.
Note:
The Safety switch is not designed to be
used as a normal way of interlocking
the KCM. It is used for safety control
only.
15
MDU SAFETY
RELAY
• Safety relay failed to close contacts
on power up and contacts remained
closed after power down.
16
MOTOR/ENCDR
FAIL
• Dual tach signals connected, one
failed.
• Over-voltage on drive power supply.
• Motor voltage applied but no speed
feedback.
• Drive temperature > 85 deg. C.
17
MDU
UNCONTROLLED
• Speed feedback but no motor
voltage applied.
18
MDU EEPROM
FAILED
• EEPROM checksum failed.
19 MDU DRIVE
FAILED
