Remedy: De-activate the measuring probe evaluation (BI: p2509 = 0 signal).
Re alarm value = 6:
Set the input terminal for the measuring probe (p0488, p0489 or p2517, p2518).
Re alarm value = 4098:
Check the Control Unit hardware.
Re alarm value = 4100:
Reduce the frequency of the measuring pulses at the measuring probe.
Re alarm value > 50000:
Set the clock cycle ratio of the measuring clock cycle to the position controller clock cycle to an integer
multiple.
To do this, the currently effective measuring clock cycle can be determined from the alarm value as
follows:
Tmeas[125µs] = alarm value - 50000.
With PROFIBUS, the measuring clock cycle corresponds to the PROFIBUS clock cycle r2064[1].
Without PROFIBUS, the measuring clock cycle is an internal cycle time that cannot be influenced.
207499 <location>EPOS: Reversing cam approached with the incorrect
traversing direction
Message -
value:
Drive object: SERVO, VECTOR
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: The reversing cam MINUS was approached in the positive traversing direction or the reversing cam
PLUS was approached in the negative traversing direction.
See also: p2613 (EPOS search for reference reversing cam minus), p2614 (EPOS search for refer-
ence reversing cam plus)
Remedy: - check the wiring of the reversing cam (BI: p2613, BI: p2614).
- check the traversing direction to approach the reversing cam.
207500 <location>Drive: Power unit data set PDS not configured
Message Drive data set: %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Only for controlled line supply infeed/regenerative feedback units:
The power unit data set was not configured - this means that a data set number was not entered into
the drive data set.
Fault value (r0949, interpret decimal):
Drive data set number of p0185.
Remedy: The index of the power unit data set associated with the drive data set should be entered into p0185.
207501 <location>Drive: Motor Data Set MDS not configured
Message Drive data set: %1
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Only for power units:
The motor data set was not configured - this means that a data set number was not entered into the
associated drive data set.
Fault value (r0949, interpret decimal):
The fault value includes the drive data set number of p0186.
Remedy: The index of the motor data set associated with the drive data set should be entered into p0186.
