Description of error/fault
Module cannot be configured
Module parameters can be set but
module signals "Abort" (red "ABT" LED
lights up).
Motor "howls" but does not move.
Motor jerks and remains still.
Motor accelerates and then remains still
and howls.
The signals are present at the output of
the IP but the motor does not move.
No output signals can be measured
although the distance to go has been
counted.
The module does not switch to the
"Pulse output" status in the case of
"Forwards" or "Backwards" mode.

Possible sources of error
-
Module addressing incorrect
- IP 267 has been configured using a programmer with
the "Force variable" function or using an OP
( Notes 5.5)
- Old configuration has not been deleted
- External STOP, limit switch or emergency limit swich
(PD) active
- IP267 has been configured using a programmer with
the "Force variable" function or using an OP
( Notes 5.5)
Start/stop rate or acceleration too high
Frequency increase too high (time intervals too
small). Note resonant frequencies of drive
Output frequency or load torque too high. Voltage
for operating motor is too low
-
Signal cables to IP connector have been crossed.
- Does the power section need a separate enable
signal?
- Special voltage V not connected correctly.
S
- External limit switch (PD) active
- External STOP active
- REF input active and the RPA (reference point
approach) set
- Limit switch start (I -) or end (I+) has already been
actuated in backwards or forwards mode
- Time interval (TI) has been set equal to zero in the
configuring data
- "Forwards" or "Backwards" mode has already been
selected so that the module now receives no valid
traversing command.
