DSQC1000 ABB robot host 3HAC042766-001
Technical data of product parameters
Error message if the servo amplifier is to bring the drive to a standstill: Error message F19 is output if an input phase is missing. The servo amplifier is disabled and the
BTB contact opens. Where the factory setting is unchanged 3HAC042766-001 the motor is braked using the set “EMERGENCY STOP RAMP”.
Behavior when undervoltage threshold is reached
If the undervoltage threshold is undershot in the DC bus link (the threshold value
depends on the type of servo amplifier), the error message 3HAC042766-001 is
displayed. The drive response depends on the 3HAC042766-001 and STOPMODE setting.
Behavior with enabled “holding brake” function
Servo amplifiers with an enabled holding brake function have a special procedure for
switching off the output stage ( p. 28). Removing the ENABLE signal triggers electrical
braking.
As with all electronic circuits, the general rule applies that there is a possibility of the internal “holding brake” module failing. Functional safety, e.g. with hanging load (vertical
axes), requires an additional mechanical brake which must be safely operated, e.g. via
the Safety Card S1-2.
Behavior of the safety function STO
With the functional safe restart lock STO, the drive can be secured on standstill using its
internal electronics so that even when power is being supplied, the drive shaft is protected against unintentional restart. The chapter “Safety function STO” describes how to use
the STO function. See page 37 onwards.
