Parameter Function
P1210 = 5:
The inverter will acknowledge the faults F3 etc. at power on after blackout and restarts the inverter. It is
necessary that the ON command is wired via a digital input (digital input).
P1210 = 6:
The inverter will acknowledge the faults (F3 etc.) at power on after blackout or brownout and restarts the
inverter. It is necessary that the ON command is wired via a digital input (digital input). Setting 6 causes the
motor to restart immediately.
P1210 = 7:
The inverter will acknowledge the faults (F3 etc.) at power on after blackout or brownout and restarts the
inverter. It is necessary that the ON command is wired via a digital input (digital input). Setting 7 causes the
motor to restart immediately.
The difference between this mode and Mode 6 is that the fault status bit (r0052.3) is not set until the num-
ber of restarts defined by P1211 have been exhausted.
Flying start must be used in cases where the motor may still be turning (e.g. after a short mains break) or
can be driven by the load (P1200).
P1210 = 8:
The inverter will acknowledge the fault (F3) at power on after blackout or brownout and restarts the inverter.
It is necessary that the ON command is wired via a digital input (DI). Setting 8 causes the motor to restart
immediately. The interval between restarts is determined by P1214.
P1211 Number of restart
attempts
Specifies number of times inverter will attempt to restart if automatic restart P1210 is activated.
P1212 Time to first restart [s]
Selects the time before the inverter is restarted for the first time if automatic restart P1210 is activated.
P1213 Restart time increment
[s]
Selects the increment amount of the restart time for each restart of the inverter if automatic restart P1210 is
activated.
P1214 Restart time interval
[s]
Selects the restart interval when using P1210=8.
P1215 Holding brake enable
Enables / disables holding brake function. The motor holding brake (MHB) is controlled via status word 1
r0052 bit 12. This signal can be issued via:
status word of the serial interface (e.g. USS)
•
digital outputs (e.g. DO1: ==> P0731 = 52.C (r0052 bit 12))
•
0
1
Caution: If the inverter controls the motor holding brake, then a commissioning may not be carried out for potentially
hazardous loads (e.g. suspended loads for crane applications) unless the load has been secured.
It is not permissible to use the motor holding brake as working brake, as it is generally only designed for a
limited number of emergency braking operations.
P1216 Holding brake release
delay[s]
Defines period during which inverter runs at minimum frequency P1080 before ramping up.
