Acknowl.: Immediate
F7900
Drive: Motor blocked
Reaction: OFF2
Cause:
Motor operates longer at the torque limit than the time specified in p2177 and below the
speed threshold set in p2175.
Remedy:
- Check free rotation of motor.
- Check torque limit: r1538 for positive direction of rotation, r1539 for negative direction of
rotation.
- Check setting parameters p2175 and p2177 and correct if necessary.
Acknowl.: Immediate
F7901
Drive: Motor overspeed
Reaction: OFF2
Cause:
The maximum permissible positive or negative speed has been exceeded.
The maximum permissible positive speed is calculated as follows: Minimum(p1082,
CI:p1085) + p2162. The maximum permissible negative speed is calculated as follows:
Maximum(-p1082, CI:1088) - p2162.
Remedy:
In positive direction:
-r1084 check and if nec. correct p1082, CI: p1085 and p2162.
In negative direction:
-r1087 check and if nec. correct p1082, CI: p1088 and p2162.
Acknowl.: Immediate
A7910
Drive: Motor Overtemperature
Cause:
Motor temperature has exceeded the alarm threshold parameterized in p0604.
The reaction set in p0610 is initiated:
See also: p0610
Alarm value
(r2124):
1: No output current reduction.
2: Output current reduction active.
Remedy:
- Check motor load.
- Check motor ambient temperature.
F7950
Drive: Motor parameter defective
Reaction: NONE
Cause:
Wrong motor parameters have been entered during commissioning, e. g. p0300 = Motor
type = 0 = No motor.
See also: p0300, p0301, p0304, p0305, p0307, p0310, p0311, p0314, p0316, p0320, p0322,
p0323
Fault value
(r0949):
Fault value contains affected parameter number.
