Brake Sequence
WARNING! Sudden Movement Hazard. Rapid deceleration may cause the drive to fault on an overvoltage condition, resulting in death
or serious injury due to an uncontrolled motor state. Be sure to set an acceptable deceleration time in parameter C1-09, Fast Stop
Ramp, when using the fast-stop feature.
NOTICE: Always turn off the RUN command before changing the setting of parameters d1-18 (Speed Reference Selection Mode), b1-
01 (Speed Reference Selection), or H1-
(Multi-Function Digital Inputs). If the RUN command is on when changing any of these
settings, the motor may unexpectedly start running, and could result in injury.
The drive supports two types of brake sequences, one with torque compensation at start using an analog input terminal
(H3-
= 14) and the other without torque compensation at start.
Brake Sequence without Torque Compensation
To configure the brake sequence operation without torque compensation, do not set any analog input terminals for
“Torque compensation” (H3-
= 14).
