4.3.2.2 Digital inputs
ENABLE (X3/12)
Functions:
}
A "1" signal enables the inverted rectifier of the servo amplifier in order to drive the mo-
tor.
} The enable is only possible if the input STO-ENABLE for the safety function is connec-
ted in accordance with the application (see section entitled: "Digital input STO-ENABLE
(X4/5)".
}
In a disabled condition ("0" signal), the connected motor is torque-free.
} PLC-compatible (IEC 61131-2 Type 1), volt-free, reference earth is DGND
Further information and connection examples can be found in this chapter under "Safety
function STO".
Setting:
} A software enable is also required in the commissioning software (logic AND connec-
tion).
} The enable can also be permanently activated ("Basic Setup" window in the PDrive
commissioning software).
Digital inputs DIGITAL-IN1 ... 4 (X3/8 ... 11)
Functions:
}
These fast inputs are suitable for latch functions or rapid feedback signals, for example.
}
These inputs can be assigned to evaluate limit switches (PSTOP and NSTOP), for ex-
ample.
}
You can use the digital inputs to initiate pre-programmed functions stored in the servo
amplifier.
}
PLC-compatible (IEC 61131-2, Type 1), volt-free, reference earth is DGND
Setting:
}
Select the required function in the PDrive commissioning software ("Digital I/O" win-
dow).
}
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).
Safety function STO, digital input STO-ENABLE (X4/5)
The digital input STO-ENABLE is used to shut down the inverted rectifier safely.
} The safety function STO is triggered through a single channel.
