4 Technical description
4.1 Input and output signals
Connection Supply
PIN 3 Power supply (see technical data)
PIN 4 0 V (GND) connection.
Connection Analogue signals
PIN 9 / 10 External speed demand (V), range
0… 10 V or 4… 20 mA (scalable)
PIN 13 Position demand value (W),
range 0… 10 V or 4… 20 mA (scalable)
PIN 14 Analogue position actual value (X),
range 0… 10 V or 4… 20 mA (scalable)
PIN 11 / PIN 12 0 V (GND) connection for analogue signals
PIN 15 / 16 Valve control signal.
Type of signal and polarity can be selected by the parameter SIGNAL:U.
Connection Digital inputs and outputs
PIN 8
Enable input:
This digital input signal initializes the application and error messages are deleted. The
controller and the READY signal are activated. The output signal to the control element is
enabled.
The actual position is accepted as the command position and the drive remains stationary
under control at this position.
If the input is disabled, the output (control signal) is switched off(disabled). Take care of the
EOUT-command!
PIN 7 START (RUN) input:
The position controller is active and the external analogue demand position is accepted as
the demand value. If the input is disabled during the movement, the system is stopped
within the set emergency stopping distance (D:S).
PIN 6
HAND + input:
Manual operation (START = OFF): the drive moves at the programmed speed in the
programmed direction. After deactivation, the actual current position is accepted as the
demand position. The START (RUN) input has priority over the HAND+ input.
If the sensor signal is missing (external ENABLE signal = ON), the drive can be operated in
manual mode.
PIN 5
HAND - input:
Manual operation (START = OFF); the drive moves with the programmed speed in the
programmed direction. After deactivation, the actual current position is accepted as the
required position. The START (RUN) input has priority over the HAND- input.
If the sensor signal is missing (external ENABLE signal = ON), the drive can be operated in
manual mode.
PIN 1
READY output:
ON: The module is enabled; there are no discernable errors.
OFF: Enable (PIN 8) is disabled or an error (sensor or internal error) has been detected.
PIN 2 STATUS output:
ON: INPOS message.
The axis is within the INPOS window.
OFF: INPOS message. The axis is outside the INPOS window.
