Reduce acceleration and deceleration values.
Check rated current.

Check setting of P570 (temperature evaluation).
Check setting of P617 (for KTY or PT1000).

Comply with permissible ambient conditions.
Ensure sufficient cooling.
For an asynchronous motor, switch to control accord-

Check P418 (Maximum frequency).
Check acceleration and deceleration values.
Set P475 and P492 to the appropriate reference fre-

For definition of reference value via multifunction
input: For P452 (terminal X12.3) and P562 (terminal
X12.4), select the correct signal to set the reference
value ("1 - voltage" or "2 - current").
Check values for P420 (acceleration clockwise) and
P422 (acceleration anticlockwise).

For high torques at low speed, field-orientated con-
trol (DMC) may be suitable. Set P30 to 410 (asyn-
