5.1 Initial switch-on
Stop!
Prior to initial switch-on of the controller, check the wiring for completeness,
short-circuit, and earth fault:
( Power connection:
- Supply via terminals L1, L2 and L3
- Separate field supply (if available)
( Field connection
( Armature connection
( Feedback system (resolver, incremental encoder, ¡)
( Control terminals:
- Controller enable: Terminal X2/28 (reference potential: X2/39)
- Selection of direction of rotation Terminal X2/21 or X2/22
(reference potential: X2/39)
- Setpoint selection
- with internal voltage supply: bridge between X2/39 and X3/40
( Maintain the switch-on sequence!
Note!
( All controllers described are factory set. A DC shunt motor with attached
tacho can be driven as a speed-controlled drive with tacho feedback
without further settings after entering the rated field current (see nameplate).
The motor must comply with the following:
- V
mains
= 420V
- n
rated
= 3000 rpm
- V
tacho
= 20V / 1000 rpm
( Simple adaptation to other machine data or special requirements: Use the
following for commissioning:
- Operating unit of the controller or
- LEMOC2 (PC program by LENZE)
