Release of Direction of Rotation In case of analog setpoint value setting and set value-dependent setting of direction
of rotation (oP.0 = 2) no Low Speed (LS) condition is available. Therefore following
measures must be taken in order for the braking control to work:
- adjust di.20 to „2“ (release of direction of rotation)
- the release signal is given by adjusting any chosen direction of rotation at the terminal
strip
or
- digital with any chosen direction of rotation (oP.3 = „1“ oder „2“)
The direction of rotation is only released. The adjustment is still done by way of the
setpoint value.

Starting Frequency (Pn.54)
Stopping Frequency (Pn.57)
The adjustable starting and stopping frequencys stands in direct connection with the
required holding torque. The presetting according to following formula applies to the
rated motor torque:
(no-load motor speed-rated motor speed) x rated motor frequency
Start-/Stop frequency=
rated motor speed
(1500 rpm
- 1420 rpm ) x 50Hz
Example: = 2,67 Hz
1420 rpm
The direction in which the holding shall be effective is defined by the sign of the
frequencies. The parameters are set programmable.
