F7820/7840-7841/7850-7860 - Siemens SINAMICS G150 Operating Manual

11/03
Remedy: Connect the original power section and activate the control unit again (POWER ON) or set
p0201 = r0200 and initiate commissioning with p0010 = 0.
If the new power section is accepted, the current limit p0640 can be reduced by means of a
lower maximum power section current (r0209) (torque limits are retained).
If the motor is replaced in addition to the power section, the motor must be re-commissioned
(e.g. via p0010=1).

F7841
Drive: Infeed signal Ready in operation canceled
Reaction: OFF2
Cause: Infeed has canceled the ready signal during operation.
- Wrong interconnection of binector input for ready signal (p0864).
- The enable signals for the infeed had been deactivated.
- Infeed removes the ready signal on account of an error.
- If this drive is to be used to generate support for the DC link,
the error reaction should be set to no reaction if the motor module is to continue to operate.
Remedy: - Check interconnection of binector input for ready signal for infeed (p0864).
- Check enable signals for infeed and activate if necessary.
- Correct fault in infeed and acknowledge message.
- If this drive is to be used to generate support for the DC link, the error reaction should be
set to no reaction if the drive is to continue to operate when the DC link voltage breaks
down.
