207110 <location>Drive: Sampling time and basic clock cycle do not match
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The parameterized sampling times do not match the basic clock cycle.
Fault value (r0949, decimal):
The fault value specifies the parameter involved.
See also: p0110, p0111, p0115
Remedy: Enter the current controller sampling times so that they are identical to the basic clock
cycle, e.g. by selecting p0112. Note which basic clock cycle is selected in p0111.
The sampling times in p0115 can only be changed manually in the sampling times preset
"Expert" (p0112).

207111 <location>Drive: POWER ON due to sampling times
Reaction: OFF2 (DCBRAKE, OFF1)
Acknowledge: POWER ON
Cause: It is not possible to change the sampling times p0112, p0115 in operation. POWER ON is
required.
Fault value (r0949, decimal):
The fault value specifies the parameter involved.
Remedy: - save (p0009 = 0 and p0977 = 1).
- carry-out a POWER ON.
207200 <location>Drive: Master control ON/OFF1 command present
Reaction: NONE
Acknowledge: NONE
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 (actual CDS) as well as p3982 bit 0 must be 0.
207210 <location>Master control PC/AOP inhibited
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The transfer of master control is disabled via binector input p3985.
Remedy: Change the signal via binector input p3985.
207220 <location>Drive: Master control by PLC withdrawn in operation
Reaction: OFF1 (NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: The "control by PLC" signal was withdrawn in operation.
- interconnection of the binector input for "control by PLC" is incorrect (p0854).
- the higher-level control has withdrawn the "control by PLC" signal in operation.
- data transfer via the fieldbus (master - drive) was interrupted in operation.
Remedy: - check the interconnection of the binector input for "control by PLC" (p0854).
- check the "control by PLC" signal and, if required, switch-in.
- check the data transfer via the fieldbus (master - drive).
Note:
If the drive should continue to operate after withdrawing "control by PLC" then fault
response must be parameterized to NONE.
207300 <location>Drive: Line contactor feedback signal missing
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
