3.) The possibility of initiating or reacting via mixed I/O / CSB and high-speed data channel:
•
•
4.) The possibility of programming operating characteristics via G commands (please refer to
Programming Guide for exact description):

Internal sources:
Examples of important internal errors are:
• ZK1 messages of 611D drive such as open cable, power section failure, etc.
• NCK alarms such as CPU failure, watchdog, emergency retraction threshold, mode group
stop alarms, etc.
• PLC alarms such as CPU failure, EMERGENCY STOP, etc.
Details about individual error statuses can be found in the error descriptions.
Error sources which are directly related to the drive are explained in more detail below:
• Mains buffering and mains failure detection
• DC link overvoltage limitation by means of a pulsed resistor module
• DC link undervoltage monitoring
• DC link buffering and monitoring of generator minimum speed limit
• Communications/control failure
• Control/unit detects error/request and specifies "Extended stop and retract" as
autonomous drive function
