• Description of the special functions available at the digital inputs (43 to 46)
Start switch: Continuous start command. If more than one input is programmed for start switch, they are in logical
AND relation. All of them must be true for effecting a start command.
Start push button: Pulse type start command. If more than one input is programmed for start push button, they
are in logical OR relation. If any of them is true start command will be sent out.
Reversing switch: Activating the input results in a reversing command. If more than one input is programmed for
reversing switch, then activating each further input results in reversing the direction of the rotation. Example: with
two digital inputs programmed for reversing switch, activating both inputs results in reversing command, that is, the
original direction will be valid.
Jogging: Usually used for adjusting the machinery, starts the motor with the frequency set in menu
Active is from stop state only.
External error: Causes the appliance to stop with running out on error message (e.g. motor thermal switch,
emergency off, etc.)
Error acknowledgement: Acceptance of the error messages, removal of the disable state.
Stop closing: With closing contact causes the motor to stop according to the preset stopping mode.
Stop opening: With opening contact causes the motor to stop according to the preset stopping mode.
Free run: Causes the motor to stop with running out. When activated, the frequency converter allows the motor to
stop freely.
DC brake: Causes the motor to stop with DC braking. When activated in stop state, the resulting standing torque
permits achieving hold function.
F fixed: The appliance goes to the frequency preset in menu
value.
Motor potentiometer up: With motor potentiometer reference signal, input for increasing the reference signal.
Motor potentiometer down: With motor potentiometer reference signal, input for decreasing the reference signal.
Control/Regulation: Dynamic changeover of the operation modes.
Analogue input swap: Swaps the analogue inputs with each other.
