I/O simulation
Danger to life due to rotating motor with loss of inverter control
If the inverter is started via I/O simulation and the IOP is removed from the inverter, the
inverter, and therefore the motor, cannot not be stopped. When I/O simulation is active, the
inverter can only be stopped via the I/O simulation. This can result in death or severe
physical injury.
• Do not remove the IOP from the inverter as long as the I/O simulation is activated.
Digital and analog inputs/outputs without external signals can
be simulated in the "I/O simulation" screen. This function is
extremely useful, especially during commissioning and trou-
bleshooting since any situation can be simulated without wir-
ing, tools or external devices.
Example:
• A digital input can be set without requiring terminal wiring to "High".
• An analog input or output can be set to any value without requiring terminal wiring.
• A digital output can be set to "High".
This screen offers the following options:
• I/O – three I/Os can be simulated (two digital I/Os and one analog I/O).
• State – the state of the input or output is displayed in real time. If the square is displayed
dark, the input or output signal is available. No changes can be made in this screen area.
• Simulation – the current state of the input or output is displayed in this screen area. These
states can be changed.
Proceed as follows to perform an I/O simulation:
1. Turn the navigation wheel until the desired digital input or output is displayed in the first
field.
2. Press OK.
3. The appropriate control field is marked.
4. Turn the navigation wheel until the desired control signal is displayed.
5. Press OK.
6. Repeat this action until all fields contain the desired settings.
7. The "Activate simulation" entry is then marked.
8. Press OK. The simulation starts.
9. "Deactivate simulation" is marked while the simulation is running – press OK to stop the
simulation.
