Goodrive270 series VFD for fan and pump
electric shock may occur. Do not touch the motor before autotuning is
completed.
 If the motor has been connected to a load, do not carry out rotary autotuning.
Otherwise, the VFD may malfunction or may be damaged. If rotary autotuning is
carried out on a motor which has been connected to a load, incorrect motor
parameter settings and motor action exceptions may occur. Disconnect from the
load to carry out autotuning if necessary.
The VFD can drive both AMs and SMs, and it supports two sets of motor parameters, which can be
switched over by multifunction digital input terminals or communication modes.

The control performance of the VFD is based on accurate motor models. Therefore, you need to carry
out motor parameter autotuning before running a motor for the first time (taking motor 1 as an
example).
