300503 Meas. circuit error phase current S
Scan
Cyclic after control power up
S
Effect
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled.
S
Power On error
Explanation
Phase current S is greater than or equal to 1.05 times the value of the maximum permissible power section current
MD 1107. Serious error has occurred in the actual current value circuit.
S
Check maximum power section current MD1107
S
Defective actual current value circuit
Remedy
Check maximum power section current MD1107; replace 611D hardware if necessary
Note
Applies up to SW 4 (611–D: up to SW 2.6)
300504 Meas. circuit error motor (inc.)
Scan
Cyclic after control power up
S
Effect
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled.
S
Power On error
S
Explanation
Encoder faulty
S
Motor encoder not connected
S
Motor encoder cable faulty
S
Module faulty
Remedy
Eliminate cause; replace motor/611D hardware if necessary
Note
Applies as from SW 3
300505 Measuring circuit error abs. track
Scan
Control power up or cancellation of the Parking Axis function
S
Effect
Pulse suppression, motor runs down
S
SIMODRIVE_READY and DRIVE_READY are cancelled.
S
Power On error
Explanation
Error on the absolute track or measured value acquisition of optical encoder
S
Absolute value encoder defective
S
Motor encoder not connected
S
Motor encoder cable faulty
S
Module faulty
S
Consider MD1023 (IMS) and MD1033 (DMS)
Remedy
Eliminate cause; replace motor/611D hardware if necessary
Note
Applies as from SW 3
