A13001 Error in license checksum
Drive object: A_INF, B_INF, CU_LINK, CU_S, DMC20, SERVO, S_INF, TB30, TM15, TM15DI_DO, TM17, TM31, TM41,
TM54F_MA, TM54F_SL, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: When checking the checksum of the license key, an error was detected.
Remedy: Compare the license key (p9920) entered with the license key on the certificate of license.
Re-enter the license key and activate (p9920, p9921).
F30001 Power unit: Overcurrent
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The power unit has detected an overcurrent condition.
- closed-loop control is incorrectly parameterized.
- motor has a short-circuit or fault to ground (frame).
- V/f operation: Up ramp set too low.
- V/f operation: Rated motor current is significantly greater than that of the Motor Module.
- infeed: High discharge and post-charging current for line supply voltage interruptions.
- infeed: High post-charging currents for overload when motoring and DC link voltage dip.
- infeed: Short-circuit currents at power-on due to the missing commutating reactor.
- power cables are not correctly connected.
- power cables exceed the maximum permissible length.
- power unit defective.
Additional causes for a parallel switching device (r0108.15 = 1):
- a power unit has tripped (powered-down) due to a ground fault.
- the closed-loop circulating current control is either too slow or has been set too fast.
Fault value (r0949, interpret bitwise binary):
Bit 0: Phase U.
Bit 1: Phase V.
Bit 2: Phase W.
Remedy: - check the motor data - if required, carry out commissioning.
- check the motor circuit configuration (star-delta).
- V/f operation: Increase up ramp.
- V/f operation: Check the assignment of the rated currents of the motor and Motor Module.
- infeed: Check the line supply quality.
- infeed: Reduce the load when motoring.
- infeed: Correct connection of the line commutating reactor.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
- replace power unit.
For a parallel switching device (r0108.15 = 1) the following additionally applies:
- check the ground fault monitoring thresholds (p0287).
- check the setting of the closed-loop circulating current control (p7036, p7037).
F30002 Power unit: DC link voltage, overvoltage
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The power unit has detected an overvoltage condition in the DC link.
- motor regenerates too much energy.
- line supply voltage too high.
- when operating with a VSM, the phase assignment L1, L2, L3 at the VSM differs from the phase assignment at the
power unit.
Fault value (r0949, interpret decimal):
DC link voltage [1 bit = 100 mV].
For SINAMICS GM/SM, the following applies:
Fault value (r0949, interpret decimal):
32: Overvoltage in the negative partial DC link (VdcP)
