3.7 Main Menu - Digital In/Out - Group 5
3.7.1 5-** Digital In/Out
Parameter group for configuring the digital input and output.
3.7.2 5-0* Digital I/O Mode
Parameters for configuring the input and output using NPN and PNP.
5-00 Digital I/O Mode
Option: Function:
Digital inputs and programmed digital outputs are pre-programmable for operation either in PNP or
NPN systems.
[0] * PNP - Active at 24V Action on positive directional pulses (0). PNP systems are pulled down to GND.
[1] NPN - Active at 0V Action on negative directional pulses (1). NPN systems are pulled up to + 24 V, internally in the
frequency converter.
NB!
This parameter cannot be adjusted while the motor is running.
5-01 Terminal 27 Mode
Option: Function:
[0] * Input Defines terminal 27 as a digital input.
[1] Output Defines terminal 27 as a digital output.
Please note that this parameter cannot be adjusted while the motor is running.
5-02 Terminal 29 Mode
Option: Function:
[0] * Input Defines terminal 29 as a digital input.
[1] Output Defines terminal 29 as a digital output.
This parameter cannot be adjusted while the motor is running.
