Drive systems

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)

sp_kh_Antriebssystem2_935x460

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
  • Acceleration and deceleration times in the range 10 sec.
  • Position the shaft in a fixed position
  • Speed monitor or “speedometer box” required
  • Messages from “sunk” and “load limit” with “event log” optional module
