Function Group Parameters
FUNCTION-00 (40161)
Start Mode
Value: 0: Accel
1: Flying Start
2: DC Brake then Start
Default: 0
Start Mode
determines what happens when a Start Command is received.
0: Accel, follows the
Acceleration Profile
(DRIVE-12) from zero speed.
1: Flying Start, determines the speed of a freewheeling motor, and resumes the Accel-
eration Profile from that point. Used in fan type applications (starting in a spinning
load).
2: DC Brake then Start, the drive applies a DC current to brake the motor before start-
ing a normal acceleration profile from zero speed. Used in fan type applications where
the fan may be freewheeling backward, and needs to be stopped before restarting the
drive.
FUNCTION-01 (40068)
Stop Mode
Value: 0: Coast to Stop
1: Decel
2: Coast then DC Brake
3: Decel then DC Brake
Default: 1
0: Coast to Stop, disables the output of the drive, allowing the motor to coast to a stop.
1: Decel, follows the
Deceleration Profile
(DRIVE-14) to zero speed.
2: Coast then DC Brake, the drive allows the motor to coast before applying a DC cur-
rent to brake the motor. The amount of time coasting is defined by the
Coast to Brake
Time
(FUNCTION-06).
3: Decel then DC Brake, follows the
Deceleration Profile
(DRIVE-14) until applying a
DC current to brake the motor. The transition from deceleration to braking occurs when
the drive output reaches the value defined by the
Decel to Brake Frequency
(FUNC-
TION-09).
FUNCTION-02 (40160)
Brake Output Frequency
Value: 0.10 – 5.00 Hz
Default: 0.1
Brake Output Frequency
creates a low frequency AC output to simulate DC output for
producing braking torque.
FUNCTION-03 (40162)
Starting Brake Time
Value: 0.1 – 300.0 Seconds
Default: 0.1
When the
Start Mode
(FUNCTION-00) is set to “DC Brake then Start”, the
Starting
Brake Time
determines how long the system will apply the DC Brake (a DC current),
used to stop a freewheeling motor before starting. The amount of braking is determined
by the
Starting Brake Level
(FUNCTION-04).
FUNCTION-04 (40163)
Starting Brake Level
Value: 1 – 100%
Default: 1
When the
Start Mode
(FUNCTION-00) is set to “DC Brake then Start”, the
Starting
Brake Level
determines how much current the DC Brake will use to stop a freewheeling
motor before starting. This value represents a percentage of the
Motor Rated Current
(DRIVE-01), the duration of which is determined by the
Starting Brake Time
(FUNC-
TION-03).
FUNCTION-05 (40133)
Stop Delay Time
Value: 0.1 – 60.0 Seconds Default: 10.0
When the
Stop Mode
(FUNCTION-01) is set to any mode other than Decel, Stop Delay
Time is used to prevent the drive from being quickly restarted if the motor is still decel-
erating from a Stop command.
Stop Delay Time
imposes a delay after the drive deter-
mines that the motor has stopped, by monitoring it’s voltage and current, before it can
be started again.
