Easy startup
1. Connect the motor to the drive, checking the connection for the motor voltage rating.
2. Enter motor data from motor nameplate:
• P1-07
= motor rated voltage
• P1-08
= motor rated current
• P1-09
= motor rated frequency
3. Enable the drive by making a connection between terminal 1 and 2). The drive auto-
matically carries out a static auto-tune where the motor winding is measured. Auto-
tune is carried out only once after first comissioning.
If auto-tune does not occur, set P4-02 to "1" to enable auto-tune. For safety reasons
parameter P4-02 can only be set and enabled on the drive.
4. For high performance sensorless vector control set P1-14 to 101, P4-01 to 0 and
P4-05 = cos
Φ
/ power factor of motor (from motor nameplate).
Setting P4-02 to 1 then starts auto-tune where the motor winding is measured.
6.2.1
Terminal mode (default setting)
To operate in terminal mode (default setting):
• Ensure that P1-12 is set to 0 (default setting).
• Connect a switch between terminals 1 and 2 on the user terminal block.
• Connect a potentiometer (1 k ... 10 k) between terminals 5, 6 and 7 with the wiper
connected to pin 6.
• Close the switch to enable the drive.
• Adjust speed with the potentiometer.
CAUTION
Danger due to possible rotating shaft during auto-tune procedure.
Minor injuries.
• Uncouple the load from the motor.
• Take precautionary measures to ensure that no risk is posed by possible rotation of
the shaft.
NOTE
The default settings (P1-12 = 0 and P2-01 = 0) for the optional switch in the IP55 switch
cabinet is FWD / REV. The motor speed can be set via potentiometer.
