Motor speed does not
correspond to setpoint
•
Analogue input function set to
"Frequency additions" and another
setpoint is present
• Check P400
• Check setting of integrated
potentiometer (P1) (SK 2x5E
only)
• P420, check active fixed
frequencies
• Check bus setpoints
• Check P104 / P105 "min. /
max. frequency"
• Check P113 "jog frequency"

Motor generating a
considerable amount of
noise (at the current limit)
and "OFF" signal is
implemented at slow speed
with little or no control,
possibly with error message
3.0
• Tracks A and B swapped round by
encoder (for speed feedback)
• Incorrect encoder resolution setting
• Encoder power supply missing
• Encoder faulty
• Check encoder connections
• Check P300, P301
• Monitor via P735

Intermittent communication
error between FI and option
modules
• System bus terminating resistor not set
• Poor connection contacting
• Interference on system bus line
• Maximum system bus length exceeded
• First and last subscriber only:
Set DIP switches for
terminating resistance
• Check connections
• Connect GND of all FI
connected to system bus
• Pay attention to routing
regulations (separate routing
of signal and control cables
and mains and motor cables)
• Check cable lengths (system
bus)
