Instruction Manual

4-2 SP120 AC Drive Installation and Operation
English
E05 Internal motor
Protection
The internal electronic motor
protection has been
triggered due to overloading
of the connected motor.
Check the entry under b12 [MOTOR OVERLOAD
CURRENT]. Reduce A42 [MANUAL BOOST
VOLTAGE]. Check the motor and drive rating.
E07 Overvoltage The maximum DC Bus
Voltage has been exceeded
due to regenerative energy
from motor.
Motor regeneration has caused a bus
overvoltage. Extend the decel time.
E08 EEPROM error The EEPROM has invalid
data.
Reset EEPROM by resetting the defaults
using b84 [
RESET FUNCTIONS].
E09 Undervoltage The DC Bus voltage fell
below the minimum rated
voltage.
Monitor the incoming AC line for low voltage
or line power interruptions.
E11 Processor error There is a malfunction or
abnormality of the CPU.
Check external wiring for a possible cause. If
problems persists, have drive serviced by
authorized Reliance Electric service
personnel.
E12 External fault External fault 12 {EXT}
indication has been received
at one of the digital inputs
(C01-C05).
Remove the cause of the fault in the external
wiring and clear the fault.
E13 Unintentional
Start protection
A digital input (C01-C05)
was set to 13 {USP} and
power was restored while a
run input was active.
Check incoming line voltage for low voltage
or line power interruptions. Remove the run
command before power-up.
E14 Ground fault There is a ground fault at the
motor output terminals.
Check for a ground fault at the output
terminals.
E15 Excess input
voltage
The input voltage is higher
than permitted.
Check the incoming AC line.
E21 Overtemperature
fault
Excessive heat has been
detected inside the drive.
Clear blocked or dirty heat sink fins. Check
ambient temperature. Check for proper
clearance distances. On models with a fan,
check for fan operation. Check for excessive
motor load.
E22 Processor error There is a malfunction or
abnormality of the CPU.
Check external wiring for a possible cause. If
problems persists, have drive serviced by
authorized Reliance Electric service
personnel.
E35 PTC circuit
triggered.
The resistance from the
external thermistor was too
large. (Greater than 3 kΩ)
Check for an overload condition at the motor,
or check for proper ventilation at the motor.
E60 Communication
error
A loss of communication has
occurred.
Check communication connections.
