P1210 = 4:
For these settings it is fundamental that the inverter only restarts if it has been in a RUN state at the time
of the fault (F3). The inverter will acknowledge the fault and restarts the inverter after a brownout. It is
necessary that the ON command is wired via a digital input (DI).
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 (DI).
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 (DI). 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 (DI). 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
number 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).
P1211 Number of restart
attempts
0 - 10 3 U, T - - U16 3
Specifies number of times inverter will attempt to restart if automatic restart P1210 is activated.
P1215 Holding brake enable 0 - 1 0 C, T - - U16 2
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 Motor holding brake disabled
1 Motor holding brake enabled
Caution: 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]
0.0 - 20.0 1.0 C, T - - Float 2
Defines period during which inverter runs at minimum frequency P1080 before ramping up.
P1217 Holding time after ramp
down [s]
0.0 - 20.0 1.0 C, T - - Float 2
Defines time for which inverter runs at minimum frequency (P1080) after ramping down.
Note: If P1217 > P1227, P1227 will take precedence.
P1218[0...2] BI: Motor holding brake
override
- 0 U, T - CDS U32 /
Bin
3
Enables the motor holding brake output to be overridden, allowing the brake to be opened under separate
control.
P1227[0...2] Zero speed detection
monitoring time [s]
0.0 - 300.0 4.0 U, T - DDS Float 2
Sets the monitoring time for the standstill identification.
When braking with OFF1 or OFF3, standstill is identified after this time has expired, after the setpoint
speed has fallen below P2167. After this, the braking signal is started, the system waits for the closing time
and then the pulses are cancelled.
