Table 4.1.1: Fault Code Description
Protective function Description
Over-current
protection
Drive automatically cuts off its output, if the output current is over 200% of the
drive’s rated current.
Caution: Since there is a possibility of damage in the power module (IGBT),
DO NOT
restart the drive until properly checked. See Testing Power
Components in Chapter 4 for checking power modules.
Over-voltage
protection
Drive automatically cuts off its output if the regenerative energy from the
motor deceleration or generative load makes the DC voltage (DC Link
voltage) of the drive over 400V for 230V applications, or over 800V for 460V
applications.
Current limit
protection
Drive automatically cuts off its output if the current has over 180% of the
drives rated current during the current limit time setting. This fault is affected
by the value set in parameter H30 of the
Advanced Level
.
Heat-Sink overheat
When the drive heat-sink overheats, the temperature detection element
triggers the drive to automatically cut off its output. A failed cooling fan or a
foreign substance in the cooling fan can cause this.
EtH
Automatically shuts off the output of the drive if the condition meets the
function settings made in H31 and H32 of the
Advanced Level.
Under the
default settings, an ETH fault would occur if there is any over-current 100%
greater than the rated current and/or an overload capacity of 150% / 1 min.
Phase fault
Occurs when one (1) or more output leads to the motor are opened.
Parameters H22 and H49 of the
Advanced Level
affect how the drive
responds to a phase loss.
Low Voltage protection
A voltage drop to the drive can cause a lack of torque and/or motor
overheating. This fault automatically shuts off the output of the drive when
the DC voltage (DC Link Voltage) of the control circuit is below 200V for
230VAC applications or 400 volts for 460VAC applications.
BX protection
This fault occurs if the BX terminal is being used. A BX fault shuts off the
output of the drive when the BX terminal is ON in the driving mode and
restarts when it is OFF.
CPU error
Drive shuts off its output when there is an error in main CPU caused by
system noise. It is possible to clear the error by pressing STOP/RESET key.
Communication
Error
Displa
y
s the error in the communication between the main unit and the
ke
y
pad, which has no influence on drive operation. It ma
y
be cleared b
y
removing the keypad.
