Configuring drive data
Specify the speed limits and the direction of the output rotating field in the menu item "P-
DRIVE DATA".
1.
Determine the minimum output frequency of the output rotary field for minimum setpoint
value with the "/fmin" value. The "/fmax" value specifies the upper speed limit. For more
detailed information, refer to the section titled "Motor connection" (Page 98).
2.
Set the rotation direction under "/Rotation":
–
"CW" or "CCW" specifies the rotary field as clockwise or counter-clockwise.
–
"Both" means that the rotary field depends on the polarity of the setpoint value and
can be changed using the terminal block command "Reversing".
3.
Set the speed of setpoint changes under "P-SPEED DEFAULT/t-accel." and "P-SPEED
DEFAULT/t-decel.".
Checking all inputs and outputs
1.
Check whether signals arrive correctly at all inputs and outputs.
You can simulate all data except load-dependent data.
2.
Under "P-EXTRAS/Menu" set the value for the menu level to "Standard", in order to
increase the number of accessible parameters and thus be able to make further
parameter adjustments.

Checks with mains power supply and with motor
Perform the following tests and configurations with an uncoupled motor. This prevents
damage to the work machine in the case of errors. If test with uncouple motor are not
possible, perform the tests with coupled motor. However, increased caution is thereby
required.
Performing auto tuning
The inverter can be matched to the connected motor under "P-MOTOR DATA/Auto-Tuning".
●
Select the "Yes" option and press the "Apply" button.
–
The inverter transmits a measurement signal to the motor.
–
The inverter calculates the current total resistance of motor winding and motor supply
line from the measured values.
Checking the direction of rotation
1.
Check the rotation direction at low speed directly at the motor.
2.
In the case of "Rotation/both", check the rotation direction for both directions.
