5.4 Digital start signal and frequency set point by LED display
Connect terminal 2 with terminal 1 to give digital start signal forward and terminal 3 to 1 for
digital start signal reverse.
Output frequency can be increased and decreased by push button ”Up” and ”Down”. In
parameter P-31 the start speed can be decided either latest speed or minimum speed.

Edge-r: Startsignal on terminal 2 is activated by positive edge.
After power on must terminal go from 0 VDC to 24 VDC.
Auto-0 = Jumper between 1 and 2 or 1 to 3 starts aleays the
motor.

2: Motor accelerete to minimal frequency, P-02, at start.
3: Motor accelerete to latest speed before stop.
5.5 Start/stop by individual signals
Start is done by a pulse on one terminal and stop on a second one. Third input decides if
frequency set point is to be analogue or a PresetSpeed in P-20. If 4-20 mA signals is to be used
current must enter terminal 6 and back from terminal 7.
5.6 Control from LED display
Connect terminal 2 with terminal 1 to give digital start signal. Then set parameters as below:
