
Check the safety conditions surrounding the motor and load machineries
before autotuning as physical injury may occur due to sudden start of motor during
autotuning.

Although the motor does not run during static autotuning, the motor is stilled
supplied with power, do not touch the motor during autotuning; otherwise, electric
shock may occur.

If the motor has been connected to load, do not carry out rotary autotuning;
otherwise, misact or damage may occur to the inverter. If rotary autotuning is carried
out on a motor which has been connected to load, wrong motor parameters and
motor misacts may occur. Disconnect the load to carry out autotuning if necessary.
S1inverter can drive asynchronous motors, and it supports two sets of motor parameters, which can
be switched over by multi-function digital input terminals or communication modes.
Name
1, this parameter is used to set the proportional
coefficient of the output current closed-loop control.
Setting range: 0–5000
When IF control is adopted for asynchronous motor
1, this parameter is used to set the integral
coefficient of the output current closed-loop control.
Setting range: 0–5000
