Cause: The parameterized sampling times are not congruent with the basic clock cycle.
See also: p0110, p0111, p0115
Remedy: Enter sampling times as integral of basic clock cycle. Note which basic clock cycle is
selected in p0111. Furthermore, the sampling times in p0115 can only be changed manually
in the sampling times preset 'Expert' (p0112).

A7200
Drive: Master control ON/OFF1 command present
Cause: The ON/OFF1 command is not 0, either via binector input p0840 (current CDS) or in control
word p3982 bit 0.
Remedy: The signal at binector input p0840 (current CDS) as well as p3982 bit 0 must be 0.
F7220
Drive: PLC control removed during operation
Reaction: OFF1
Cause: PLC control signal removed during operation.
- Interconnection of binector input for PLC control wrong (p0854).
- Superimposed control has removed the PLC control signal during operation.
- Field bus connector (master drive) withdrawn during operation.
- If this drive is to continue to run after removal of PLC control , the error reaction should be
parameterized to no reaction.
Remedy: - Check interconnection of binector input for PLC control (p0854).
- Check signal PLC control and activate if necessary.
- Check field bus connector (master drive).
- If this drive is to continue to run after removal of PLC control , the error reaction should be
parameterized to no reaction.

F7300
Drive: Main contactor no checkback
Reaction: OFF2
Cause: - Unable to activate the main contactor within the time parameterized in p0861.
- Unable to deactivate the main contactor within the time parameterized in .
- Main contactor closed during operation.
- Main contactor activated although converter is deactivated.
Remedy: - Check setting of p0860.
- Check feedback loop of main contactor.
- Increase monitoring time in p0861.

F7320
Drive: Automatic restart aborted
Reaction: OFF2
Cause: - The specified number of restart attempts (p1211) has been used up since the alarms could
not be acknowledged within the waiting time defined by p1212 and p1213.. On each start,
the number of restart attempts (p1211) is decremented.
- No active ON command present.
- If p1210 = 2, the start attempt is aborted because at least one alarm is present.
- If p1210 = 3 or 4, the start attempt is aborted because at least one alarm is present
following activation of the electronics.
- The monitoring time of the power section (p0857) has expired.
- Restart is not possible after incorrect motor identification.
Remedy: - Increase number of restart attempts (p1211). The current number of restart attempts is
displayed in r1214.
- Increase the waiting time in p1212 and/or in p1213.
- Apply an ON command (p0840).
- Increase the monitoring time of the power section in p0857 or deactivate.

A7350
Drive: Probe terminal parameterized as digital output
Cause: Probe is connected to a bidirectional digital input/output and the terminal is set as output.
