Table 91: Cycling shutdown messages
Message Description
VSD – LOGIC BOARD
PROCESSOR
This shutdown is generated if a communications problem occurs between the two
microprocessors on the drive logic board.
VSD – LOW DC BUS VOLTAGE
This shutdown is generated any time after the pre-regulation state has generated the
correct DC link voltage setpoint and then the DC link voltage drops to a minimum value.
This value is based on the drive model number.
Drive model DC link voltage setpoint
0490B 755
This shutdown often occurs when there is a sudden change in the input voltage due to
storms, utility power problems, or site power problems.
VSD – LOW PHASE A INPUT
BASEPLATE TEMPERATURE
The temperature of the input baseplate phase A has decreased below the low limit of
34°F (1.1°C). All phase temperatures must increase above the fault-reset threshold of 42°F
(5.5°C) for this fault to clear. The cooling fans and pumps turn on while this shutdown is
present. They turn off when the temperature rises above the fault-reset threshold.
VSD – LOW PHASE B INPUT
BASEPLATE TEMPERATURE
See the previous message, VSD – LOW PHASE A INPUT BASEPLATE TEMPERATURE .
VSD – LOW PHASE C INPUT
BASEPLATE TEMPERATURE
See the previous message, VSD – LOW PHASE A INPUT BASEPLATE TEMPERATURE .
VSD – LOW PHASE A MOTOR
BASEPLATE TEMPERATURE
The control center determines this fault when the temperature of the motor baseplate
phase A has decreased below the low limit of 34°F (1.1°C). All phase temperatures
must increase above the fault-reset threshold of 42°F (5.5°C) for this fault to clear. The
cooling fans and pumps turn on while this shutdown is present. They turn off when the
temperature rises above the fault-reset threshold.
VSD – LOW PHASE B MOTOR
BASEPLATE TEMPERATURE
See the previous message, VSD – LOW PHASE A MOTOR BASEPLATE TEMPERATURE .
VSD – LOW PHASE C MOTOR
BASEPLATE TEMPERATURE
See the previous message, VSD – LOW PHASE A MOTOR BASEPLATE TEMPERATURE .
VSD – NOT RUNNING
The control center determines this fault when the variable speed drive has not reported
run state through serial communications for 8 seconds while the microboard issues a VSD
run command. The fault is released when the microboard command is Stopped State.
VSD – PHASE A INPUT DCCT
OFFSET
When the drive begins precharge, the output of the input current Direct Current Current
Transformers (DCCT) are evaluated to ensure that they are reading zero current when no
current is flowing through the DCCT. If the zero current output value is above a threshold,
then this shutdown is generated.
VSD – PHASE B INPUT DCCT
OFFSET
See the previous message, VSD – PHASE A INPUT DCCT OFFSET .
VSD – PHASE C INPUT DCCT
OFFSET
See the previous message, VSD – PHASE A INPUT DCCT OFFSET .
VSD – PHASE A INPUT GATE
DRIVER
The gate driver board for the input/rectifier monitors the power supplies within the gate
driver circuit, and confirms that the input/rectifier can be correctly controlled. If the gate
driver monitor determines that the input/rectifier cannot be correctly controlled, then the
drive shuts down and displays this message.
VSD – PHASE B INPUT GATE
DRIVER
See the previous message, VSD – PHASE A INPUT GATE DRIVER .
VSD – PHASE C INPUT GATE
DRIVER
See the previous message, VSD – PHASE A INPUT GATE DRIVER .
VSD – PHASE A MOTOR GATE
DRIVER
The gate driver board for the motor/inverter monitors the power supplies within the gate
driver circuit, and confirms that the motor/inverter can be correctly controlled. If the gate
driver monitor determines that the motor/inverter cannot be correctly controlled, then the
drive shuts down and displays this message.
VSD – PHASE B MOTOR GATE
DRIVER
See the previous message, VSD – PHASE A MOTOR GATE DRIVER .
VSD – PHASE C MOTOR GATE
DRIVER
See the previous message, VSD – PHASE A MOTOR GATE DRIVER .
