Unidrive M200-201 Quick Start Guide
Issue Number: 7
cL.A1
Analog input 1 current loss
Current loss was detected in current mode on Analog input 1
(Terminal 2).
CL.bt
Trip initiated from the
Control Word
Initiated by setting bit 12 on the control word when the control
word is enabled. Refer to the
Parameter Reference Guide
Cur.c
Current calibration range
Current calibration range error.
Cur.O
Current feedback offset error
Current offset is too large to be trimmed.
d.Ch
Drive parameters are being
changed
A user action or a file system write is active that is changing the
drive parameters and the drive has been commanded to enable.
dEr.E
Derivative file error
Contact the supplier of the drive.
dEr.I
Derivative product image error
Contact the supplier of the drive
dESt
Two or more parameters are
writing to the same destination
parameter
The
dESt
trip indicates that destination output parameters of two
or more logic functions within the drive are writing to the same
parameter.
dr.CF
Drive configuration
Contact the supplier of the drive.
EEF
Default parameters have been
loaded
The
EEF
trip indicates that default parameters have been
loaded. The exact cause/reason of the trip can be identified from
the sub-trip number (Refer to the
Control User Guide
).
Et
An External trip is initiated
The cause of the trip can be identified from the sub trip number
displayed after the trip string.
Refer to the
Control User Guide
.
FAn.F
Fan fail
Indicates the fan or fan circuitry has failed
Fi.Ch
File changed
A file has been changed, power cycle to clear the trip
FI.In
Firmware Incompatibility
The user firmware is incompatible with the power firmware.
HFxx trip
Hardware faults
Internal drive hardware fault (Refer to the
Control User Guide
).
It.Ac
Output current overload timed out
(I
2
t)
The
It.Ac
trip indicates a motor thermal overload based on the
output current and motor thermal time constant. The drive will
trip on
It.Ac
when the accumulator
gets to 100 %.
This can occur when:
•
There is excessive mechanical load
•
Ensure the load is not jammed / sticking
•
Check the load on the motor has not changed
•
Ensure the motor rated current is not zero
It.br
Braking resistor overload timed out
(I
2
t)
Braking resistor overload has timed out. This can be caused by
excessive braking resistor energy.
no.PS
No power board
No communication between the power and control boards.
O.Ld1
Digital output overload
The total current drawn from the AI-Adaptor 24 V supply or from
the digital output has exceeded the limit.
O.SPd
Motor frequency has exceeded the
over frequency threshold
Excessive motor speed (typically caused by mechanical load
driving the motor).
Oh.dc
DC bus over temperature
DC bus component over temperature based on a software
thermal model.
Oht.C
Control stage over-temperature
Control stage over-temperature detected.
Oht.I
Inverter over temperature based
on thermal model
IGBT junction over-temperature has been detected based on a
software thermal model.
Oht.P
Power stage over temperature
This trip indicates that a power stage over-temperature has
been detected.
OI.A1
Analog input 1 over-current
Current input on analog input 1 exceeds 24 mA.
