Reaction upon A: NONE
Acknowl. upon A: NONE
F07890
Internal voltage protection / internal armature short-circuit with STO active
Message value:
-
Drive object:
All objects
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The internal armature short-circuit (p1231 = 4) is not possible as Safe Torque Off (STO) is enabled. The pulses cannot be
enabled.
Remedy:
Switch out the internal armature short-circuit (p1231=0) or deactivate Safe Torque Off (p9501 = p9561 = 0).
Note:
STO: Safe Torque Off / SH: Safe standstill
F07900 (N, A) Drive: Motor blocked/speed controller at its limit
Message value:
-
Drive object:
All objects
Reaction:
OFF2 (NONE, OFF1, OFF3, STOP2)
Acknowledge:
IMMEDIATELY
Cause:
Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold in
p2175.
This signal can also be initiated if the speed actual value is oscillating and the speed controller output repeatedly goes to
its limit.
See also: p2175
Remedy:
- check that the motor can freely move.
- check the effective torque limits (r1538, r1539).
- check the parameter, message "Motor blocked" and if required, correct (p2175, p2177).
- check the inversion of the actual value (p0410).
- check the motor encoder connection.
- check the encoder pulse number (p0408).
- for SERVO with encoderless operation and motors with low power ratings (< 300 W), increase the pulse frequency (p1800).
- after de-selecting the "Basic positioner" (EPOS) function mode, check the motoring (p1528) and regenerative (p1529)
torque limit and modify again.
- blocksize device: for encoderless operation and a current controller sampling time p0115[0] < 80 µs, either set the pulse
frequency of p1800 = 1 / p0115[0] or increase the switchover speed of the model p1755.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07901
Drive: Motor overspeed
Message value:
-
Drive object:
All objects
Reaction:
Servo: OFF2 (IASC/DCBRK)
Acknowledge:
IMMEDIATELY
Cause:
The maximum permissible speed was either positively or negatively exceeded.
The maximum permissible positive speed is formed as follows: Minimum (p1082, CI: p1085) + p2162
The maximum permissible negative speed is formed as follows: Maximum (-p1082, CI: 1088) - p2162
