Description of the Interface
3.1
Voltage supply
Supply voltage for interface and encoders is made available by the frequency inverter. The
voltage to the encoder supply is switchable between 24 V (standard) and 15 V. An external
supply must be used if higher signal voltages or currents than mentioned below are re-
quired. The voltage input at X3B is used only for the HTL signal levels.
