Trial Operation - Omron VARISPEED G7 Instruction Manual

• Do not connect electromagnetic switches or contactors to the output circuits.
Setting User Constants
• Disconnect the load (machine, device) from the motor before performing rotational autotuning.
• Stay clear of the motor during rotational autotuning.

Trial Operation

• Check to be sure that the front cover is attached before turning ON the power supply.
• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared,
