MOTOR BRAKE PARAMETERS
While operating in closed loop vector mode
When operating in open loop mode (AA121 = 1 thru 9) the motor brake release and set f
It is rare for field adjustments to be made for any of these parameters. Please consult Detroit Hoist before adjusting any motor brake
parameters.
When switching between VFD Control Modes (AA121) the internal firmware will automatically assign the AL relay function CC-07 to
the default value listed below. Relay 16 can be used in tandem with AL for added safety by changing VFD parameter CC-06 to the
value set in CC-07 and moving the wire from AL1 to 16A and wiring AL1 to 16C.
IMPORTANT – When switching between VFD Control Modes (AA121) the internal program will automatically assign the AL relay
function CC-07 to the default value listed below it does NOT set CC-06 automatically.
CE-10 2.50 Hz (default)
CE-11 2.50 Hz (default)
Brake release delay time UE-25 45 ms (default)
AL relay output function CC-07 63:LOG2
Brake set delay time UE-27 45 ms
Brake release delay time UE-28 45 ms
AL relay output function CC-07 62:LOG1
The brake release delay time is used to compensate for delayed brakes and help prevent driving through the motor brake.
The brake set delay time is used to compensate for delayed brakes and help prevent nuisance brake slip detection.
