and "OFF" signal is
implemented at slow speed
with little or no control,
possibly with error message

• Analog input function set to "Frequency
additions" and another
present
• Tracks A and B swapped by encoder (for
speed feedback)
• Incorrect encoder resolution setting
• Encoder power supply missing
• Encoder faulty
• System bus terminating resistors
incorrectly set
• Poor connection contact
• Faults on system bus line
• Maximum system bus length exceeded
Check P400
•
• Check setting of integrated
setpoint is
potentiometer (P1) (only
SK 2x5E)
• P420, check active fixed
frequencies
• Check bus setpoints
• Check P104/P105 "min/max
frequency"
• Check P113 "jog frequency"
• Check encoder connections
• Check P300, P301
Monitor via P735
•
• Check encoder
• First and last subscriber only:
set DIP switches for
terminating resistor
• Check connections
• Connect GND of all VFDs
connected to system bus
• Pay attention to routing
regulations (separate routing
of signal and control cables
and power and motor cables)
• Check cable lengths (system
bus)
