The drive controller consists of two essential parts:
• power section
• control section
Power Section
The power section incorporates the control section and has the following
connections:
• mains voltage connection (at supply modules and HCS devices)
• motor connection (with optional motor holding brake and motor
temperature monitor)
• 24 V control voltage
• DC bus connection
• module bus connection for cross communication in the case of DC
bus connection with other devices
• connection for external braking resistor (at HCS devices)
