FUNCTION-06 (40156) Coast to Brake Time Value: 0.1 – 10.0 Seconds Default: 0.1
When the Stop Mode (FUNCTION-01) is set to “Coast then DC Brake”, Coast to Brake
Time allows for a programmed delay, in which the motor coasts, between pressing
“STOP” and the DC Brake being applied. This allows the magnetic field in the motor to
decay before applying the brake.
FUNCTION-07 (40157) Stopping Brake Time Value: 0.1 – 300.0 Seonds Default: 0.1
When the Stop Mode (FUNCTION-01) is set to “Coast then DC Brake” or “Decel then
DC Brake”, the Stopping Brake Time determines how long the system will apply the DC
Brake. The amount of braking is determined by the
Stopping Brake Level (FUNCTION-
08).
FUNCTION-08 (40158) Stopping Brake Level Value: 1 – 100% Default: 1
When Stop Mode (FUNCTION-01) is set to “Coast then DC Brake” or “Decel then DC
Brake”, the Stopping Brake Level determines how much current the DC Brake will ap-
ply. This value represents a percentage of the
Motor Rated Current (DRIVE-01), the
duration of which is determined by the Stopping Brake Time (FUNCTION-07).
FUNCTION-09 (40159) Decel to Brake Frequency Value: 0.10 – 300.00 Hertz Default: 20.0
When the Stop Mode (FUNCTION-01) is set to “Decel then DC Brake”, the Decel to
Brake Frequency determines the frequency at which, after following the Deceleration
Profile (DRIVE-15), DC current is applied to brake the motor.
FUNCTION-10 (40071)
Motor Thermal Overload
Enable
Value: 0 Disabled
1: Enabled
Default: Enabled
The motor overload function enables protection of the motor from thermal breakdown of
the insulation and windings. When enabled, the drive will trip when the output current
persists over the value programmed in
Motor OL Level (FUNCTION-11), for a duration
longer than that programmed in Motor OL Time (FUNCTION-12).

NOTE : Do not rely on the drive for motor overload protection when the drive is
used in a synchronous transfer application. The drive cannot monitor motor current
when the motor is transferred across the line.
