7.12.3 Analog output
The softstarter is equipped with one analog output for a
configurable analog output signal to an analog meter, or
the PLC.
The parameter analogue output type, AO type, can be
selected to show:
• Motor current, A
• Mains voltage, V
• Active power, kW
• Active power, HP
• Reactive power, kVar
• Apparent power, kVA
• Active energy, kWh
• Reactive energy, kVArh
• cos fi
• Motor temperature, %
• Thyristor temperature, %
• Motor voltage, %
• Mains frequency, Hz
• PT100 temperature, centigrade
• PTC resistance, Ohm
The voltage or current output can be set by a
configuration parameter, AO reference in the softstarter.
The selection of voltage or current must be set to adapt to
the analog meter or the PLC.
The settings are:
• 0-10V voltage output
• 0-10mA current output
• 0-20mA current output
• 4-20mA current output
AO is the referens to the output voltage in 0-100 % of the
set parameter AO max and AO min.
Example:
• AO type is set to Motor current.
• AO reference is set to 0-10V
• AO min to 0, and AO max to 3000.
This means that when the motor current is:
• 3000 A, the output voltage will be 10V.
• 0 A, the output voltage will be 0 V.
• 1500 A, the output voltage will be 5 V.
