SINAMICS V60 faults and alarms
A.8.3.1
Unable to identify the power board
Parameter validation error (CRC error, encoder type or parameter header invalid)
Unable to write data to memory
Control voltage is lower than 3.5 V.
IGBT is detected overcurrent.
Internal chip is detected overcurrent.
Grounding short circuit occurs during drive initialization
Signals from encoder phases U, V, W are detected all the same (all high or all low)
DC link voltage is higher than 405 V
IGBT current exceeds the upper limit for 300 ms
DC link voltage is lower than 200 V
A24 The difference between the position setpoint and the position actual value is greater than 1000 pulses
(1/10 rotation).
Actual motor speeds is higher than 2300 rpm
Following error exceeds the limit
Motor load exceeds nominal motor torque
Enable signal from Terminal 65 is lost during normal drive running
Replace the drive with a new one
A02 The memory is damaged due to unexpected
power-off during data saving
Restore default parameters
Replace the drive with a new one
A04
The 24 V DC supply is abnormal
Replace the drive with a new one
A05 This alarm may occur
when the DC link is
• There is a short-circuit between terminals
U, V, W and PE on the drive
• Bad grounding
• Motor insulation is broken
• The drive is broken
• Check the wiring
• Make a correct grounding
• Replace the motor with a new
one
• Replace the drive with a new
This alarm may occur
when the motor is run-
ning
A06 This alarm may occur
when the DC link is
•
There is a short-circuit between terminals
U, V, W and PE on the drive
• Bad grounding
• Motor insulation is broken
• The drive is broken
•
Check the wiring or whether
the connection to U, V or W is
broken
• Make a correct grounding
• Replace the motor with a new
one
• Replace the drive with a new
This alarm may occur
when the motor is run-
