SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Specifies number of times inverter will attempt to restart if automatic restart P1210 is activated.
Description: Enables/disables holding brake function.
The mechanical motor holding brake (MHB) is controlled via the signal of status word 1 r0052 Bit12 "Brake open".
This signal can be issued via:
• status word of the serial interface (e.g. USS)
• digitial outputs (e.g. DO0: ==> P0731 = 52.C (r0052 Bit12))
Values: 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 emergeny braking operations.
Note: In V/f control (P1300 < 20) a typical value of min. frequency P1080 for motor holding brake is the slip frequency of
the motor r0330.
In a vector control mode (P1300 = 20) the following should be valid:
• The value of the min. Frequency P1080 should be zero.
• The delay speed loss reaction should be > brake holding times (i.e. P0494 > P1216 and P0494 > P1217 )
• The delay time for motor pulled out should be > brake holding times (i.e. P2178 > P1216 and P2178 > P1217 )
Otherwise there may be encoder loss trips (F0090) when the brake is applied and pulses are enabled.
