Description
No Function
Setting to 1 resets internal kWh meter to zero (as displayed in parameter 0115 ENERGY
CONSUMPTION KWH METER and parameter 0141 ENERGY CONSUMPTION MWH METER.
Sets the fieldbus address for the ACS255
Sets the baud rate when Modbus RTU communications are used
Sets the expected Modbus telegram data format.
No Parity, 1 stop bit
No parity, 2 stop bits
Odd parity, 1 stop bit
Even parity, 1 stop bit
Sets the baud rate when CAN Open communications are used
Definition of motor set-up data.
Defines the function of the digital inputs depending on the control mode setting in
Parameter 1103 PRIMARY COMMAND SOURCE MODE.
Selects the motor control method. An autotune must be performed if setting 0, 1 or 3 is used.
This parameter should be set to the rated (nameplate) voltage of the motor (Volts).
Voltage
Note : The stress on the motor insulation is always dependant on the drive supply voltage.
This also applies in the case where the motor voltage rating is lower than the rating of the
drive and the supply of the drive.
This parameter should be set to the rated (nameplate) current of the motor.
Current
This parameter should be set to the rated (nameplate) frequency of the motor
Frequency
This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to
the default value of zero, all speed related parameters are displayed in Hz, and the slip
compensation for the motor is disabled. Entering the value from the motor nameplate
enables the slip compensation function, and the ACS255 display will now show motor speed
in estimated rpm. All speed related parameters, such as Minimum and Maximum Speed,
Preset Speeds etc. will also be displayed in Rpm.
Drive measures the motor parameters for optimum control and efficiency. Following
completion of the autotune.
Drive immediately carries out a non-rotating autotune, parameter 9910 MOTOR PARAMETER
AUTO-TUNE ENABLE returns to 0 when completed.
When operating in Vector Speed or Vector Torque motor control modes, this parameter must
be set to the motor nameplate power factor
