Name Description
Possible Causes & Corrective Action
Brk Hold Flt
The brake hold command and
the brake feedback did not
match for the time specified
with Brake Hold Time (A1)
parameter.
Check Parameter Settings
 Check the correct logic input is configured for
the correct TB1 terminal and set to MECH
BRK HOLD (C2)
 Check BRAKE HOLD SRC (C1) parameter for
the correct source of brake pick feedback
 Check BRAKE HOLD TIME (A1) parameter for
the correct brake hold time
 Wrong assignment of Normally Closed contact
mask (C2)
 Check BRK HOLD FLT ENA (C1)
Verify Brake Settings
 If drive is controlling brake, verify a logic
output is set to BRAKE HOLD (C3)
 Check for an open circuit between the brake
pick pilot relay and the logic output assigned
to brake pick control
Mechanical Brake Hold Signal Wiring
 Defective Brake Hold Coil
 Defective Brake Hold Auxiliary contactor used
for sensing the brake state
If nuisance fault, the fault can be disabled by
BRK HOLD FLT ENA (C1) parameter.
Brk Pick Flt
The brake pick command and
the brake feedback did not
match for the time specified
with Brake Pick Time
parameter.
Check Parameter Settings
 Check the correct logic input is configured for
the correct TB1 terminal and set to MECH
BRK PICK (C2)
 Check BRAKE PICK SRC (C1) parameter for
the correct source of brake pick feedback
 Check BRAKE PICK TIME (A1) parameter for
the correct brake hold time
 Wrong assignment of Normally Closed contact
mask (C2)
 Increase BRAKE PICK TIME (A1)
Verify Brake Settings
 If drive is controlling brake, verify a logic
output is set to BRAKE PICK (C3)
 Check for an open circuit between the brake
pick pilot relay and the logic output assigned
to brake pick control
Mechanical Brake Pick Signal Wiring
 Defective Brake Pick Coil
 Defective Brake Pick Auxiliary contactor used
for sensing the brake state
If nuisance fault, the fault can be disabled by BRK
PICK FLT ENA (C1) parameter.
Check Setup
This fault is logged when a new
program is loaded to the motor
side processor, and the default
data is loaded for the
parameter values.
Invalid Parameter Setup
This is an advisory fault indicating that the user
should verify the drive’s parameters or Upload a
valid parameter set using Magnetek Explorer
