GMN motor spindles are operated by means of inverters in an uncontrolled or controlled manner, each with a speed sensor (RPM sensor) or a rotary encoder.
Drive without rotary encoder
Drive with rotary encoder (C-axis operation)
Drives without controllers: Frequency control with provision of voltage from the U/F characteristics
Output frequency up to 3000 Hz1)
Setting range to about 1:10
