1 Alarms
1.5.1 Alarm description
300610 Rotor position identification failed
Scan
During the function "Rotor positon identification"
Effect
FDD only:
– Controllers are disabled, motor is braked
– SIMODRIVE_READY and DRIVE_READY are cancelled.
– Reset error
Response via MD 1613.13 configurable as from SW 4
Explanation
Rotor position could not be determined from the measuring signals, because no significant saturation effects oc-
curred.
Remedy
Increase current via MD 1019 or check whether motor is connected.
Note
Applies as from SW 6
300611 Illegal motion during rotor position identification
Scan
During the function "Rotor position identification"
Effect
for MSD only:
S
Controllers are disabled, motor is braked
S
SIMODRIVE_READY and DRIVE_READY are cancelled.
S
Reset error
Explanation
During the measurement, the motor has rotated by a value greater than that entered in MD 1020. The torsion may
have been caused by switching the motor onto a rotating motor or through the identification.
Remedy
If the torsion has been caused by the identification and if the error occurs repeatedly, reduce MD 1019 or increase
MD 1020.
Note
Applies as from SW 6
300612 Illegal current during rotor position identification
Scan
During the function "Rotor position identification"
Effect
For FDD only:
– Controllers are disabled, motor is braked
– SIMODRIVE_READY and DRIVE_READY are cancelled.
– Reset error
Explanation
1. With rotor position identification active (FDD only), the permissible current threshold (power section) was ex-
ceeded.
2. With rotor position identification active (FDD only), the maximum motor current (MD 1104) was exceeded.
Remedy
With rotor position identification active, check MD 1019 and reduce if applicable.
Note
Alarm from SW 6.1
300613 Motor temperature alarm
Scan
Cyclic after control power up
Effect
for MSD:
S
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled.
S
Reset error
for FDD:
S
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled
S
Reset error
Response via MD 1613.13 configurable as from SW 4
Explanation
Beyond the motor temperature threshold MD 1607
S
Motor overloaded
S
Machine current too great, e.g. because of incorrect motor data
S
Temperature sensor defective (motor)
S
Motor fan defective
S
Module defective
S
Fault between turns motor
Remedy
Eliminate cause or operate at MSD fixed temperature
Note: Temperature monitoring not active with fixed temperature
Note
Applies as from SW 4
