4.3.2.3 Digital outputs
Operational readiness (X3B/14, 15)
Functions:
} The servo amplifier is ready for operation when the relay contact BTB is closed.
} Operational readiness is not dependent on the ENABLE signal, I²t limitation and braking
threshold.
} If an error occurs, the relay contact opens. The output on the servo amplifier switches
off. The output is disabled and supplies no power.
} A list of error messages is available in the chapter entitled “Messages/Errors”, under
“Error messages”.
Programmable digital outputs DIGITAL-INOUT 1 / 2 (X3A/6, 7)
Functions:
} Pin 6 and 7 on X3A can either be used as a digital input or output.
} PLC-compatible (IEC 61131-2, Type 1), 24VDC, max. 100mA, volt-free
} 24V switching voltage, must be supplied externally.
Setting the parameters:
} Select whether you wish to use it as an input or output in the commissioning software
(“Digital I/O” window).
} The digital outputs can be used as signal outputs for pre-programmed functions, e.g.
"Speed below limit value".
} A list of the pre-programmed functions is available in the "Digital I/O" window of the
commissioning software.
} If a pre-programmed function has been newly assigned, the data record must be stored
in the servo amplifier's EEPROM and the device must be reset (e.g. using the commis-
sioning software PASmotion).
STO1-STATUS/STO2-STATUS (X4/8, 6)
Function:
} Signalling the status of the safety function STO
STO1-STATUS signals the status of the input STO1-ENABLE, STO2-STATUS signals
the status of the input STO2-ENABLE
– STO1-STATUS
1: STO1-ENABLE active (= "0"), power element switched off
0: STO1-ENABLE inactive (= "1"), drive in closed loop operation
– STO2-STATUS
1: STO2-ENABLE active (= "0"), power element switched off
0: STO2-ENABLE inactive (= "1"), drive in closed loop operation
