1329I-5.5 Integrated Drive/Motor — January, 2000
Keypad Redundant Start Keypad hardware malfunction. Remove power from the unit. Check
the keypad cable connection.
Reapply power to the unit.
Function Loss Open connection on Function
Loss control terminal block inputs
(terminals 7 and 11). Check and restore the Function
Loss connection on the control
terminal block (see Section 7.1).
Check the external sensors wired
into the Function Loss string.
Overvoltage High AC input line.
Deceleration time too fast or
overhauling load.
Check input line to verify voltage is
within operating specifications.
Increase deceleration time using the
accel/decel rotary switch (see
Section 8.2).
EEPROM Drive ID Contents of the EEPROM is
corrupted. Reset parameters to default
values and cycle power.
If fault persists, replace unit.
Undervoltage Low AC nput line or temporary
loss of AC input line. Check input line to verify voltage
is within operating
specifications.
Overcurrent
(Current exceeded 200% of
rated current.) Shaft rotation blocked.
Excessive driven load.
Input power is not correctly
wired to the unit.
Motor Section ground fault.
Check for obstructions to shaft
rotation.
Reduce excessive load.
Increase accel / decel time
using the accel/decel rotary
switch (see Section 8.2).
Verify input wiring is correctly
connected (see Section 5.0).
Ohm out Motor Section to check
for ground fault. Replace unit if a
ground fault is detected
.
Overtemperature Operating environment is too
hot.
Blower is blocked or not
operating.
Excessive driven load.
Check the application site and
verify the ambient temperature
is within the operating
specification.
Check for blower obstruction.
Replace blower if required.
Reduce load or make sure unit
matches the application
requirement.
