8.10 Timer Parameters (LT)
LT01 Brake Release Delay
This timer delays the release of the brake when one of the outputs is assigned as Brake
Control or Drive On and that output is used to trigger the brake release.
The LT01 Brake Release Delay timer begins after the STO Inputs and Direction
commands have been given and the current check has completed.
The Brake Control and Drive On outputs will be active after the expiration of the LT01
Brake Release Delay time.
LT02 Control Hold Off
The amount of time after a run command has been given that the drive will maintain very
low speed control gains to prevent any reaction to movement or encoder disturbance
while the brake is still set. If used, the timer must be set to expire before the brake picks.
The LT02 Control Hold Off timer begins after the STO Inputs and Direction commands
have been given. The total time the Control Hold Off is active is LT01 + LT02.
LT03 Speed Start Delay
The amount of time the drive will hold the speed command at zero. This time delay allows
the brake to release before the motor starts turning. This applies to control modes US04
Control Type = Binary Speed Selection (1), Digital Speed Selection (0), or Serial Binary
Speed DIN66019 Serv.50 (6).
The LT03 Speed Start Delay timer begins after the STO Inputs and Direction commands
have been given, current check has completed, and the LT01 Brake Release Delay timer
has expired.
For control Modes US04 Control Type = Bi-Polar Analog Speed (3), Absolute
Analog Speed (2), Serial Speed DIN66019 Service 49 (4), Serial Speed DIN66019
Service 50 (5), the profile delay is controlled externally by the controller and the
drive will not clamp the value at zero speed during this period. For these US04
Control Types, this parameter will only be used to limit the amount of time the
