Encoder interface HTL input / HTL output
2.3 Mechanical installation
All kind of works on the inverter may be carried out by authorized personnel in accordance
with the EMC and safety rules only.
• Switch inverter de-energized and await capacitor discharge time
• Pull off operator
• Remove plastic cover
• Remove fi xing bolt
• Fix interface board beginning from the socket connector straightly
• Screw in fi xing bolt
• Adjust desired supply voltage with DIL switch
• Attach plastic cover
3. 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.
