4.3 Control element
4 Function description
Setting:
 A software enable is also required in the commissioning software (log-
ic AND connection).
 The enable can also be permanently activated ("Basic Setup" window
in the PDrive commissioning software).
][Funktion_Ein_dig_X3_8_11_DD5
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 example.
 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" window).
][Funktion_Ein_Aus_Param_neu  If a pre-programmed function has been newly assigned, the data
record must be stored in the servo amplifier's EEPROM and the unit
must be reset (e.g. using the commissioning software).
][Funktion_Ein_dig_STO_ENABLE_DD5
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.
 The servo amplifier is ready for operation when there is a 24 V signal
at the input.
 If the STO-ENABLE input is open, no more power is transferred to the
motor. The drive becomes torque-free and runs down.
 In conjunction with the output from a safety relay or safety control
system, you can safely prevent the drive from restarting.
 Requirements of the output on a safety control system or safety relay:
PL d (Cat. 2) of EN ISO 13849-1, SIL CL 2 of EN/IEC 62061
 If the safety function STO is not needed, STO-ENABLE must be con-
nected directly to 24 V.
 This input is not compatible with IEC 61131-2.
 Volt-free, reference earth is XGND
