• After the Autotuning procedure, check that the motor correctly runs in both directions in MANUAL

control mode with the SPEED function and a digital speed input command in the Reference block.

• Check the response at a low speed without IDC saturation in MANUAL control (with the SPEED

function) or in AUTOMATIC control with an analog input speed command on CV of X4.

• Accurately adjust the speed loop response stability by means of the Stability gain buttons in the lower

part of the CONTROLLER module, if necessary.

• Short-circuit the CV input of the X4 connector or enter a zero speed input command in the NC to

compensate the offset of the whole system.

• Start the Offset compensation function of the ANALOG INPUT module or by means of the

OFFSET button on the amplifier front panel.

• Start the Modify function in the module ENCODER RESOLUTION and select the encoder signal

specifications on the channels A, B and Z of the connector X2 (see chapter 5.1.2).

• Select the Programmation function to initiate the new encoder output

6.3.3 Amplifier parameters saving

• Save all parameters in the amplifier EEPROM by means of the Save parameter to EEPROM

function of the FILE menu.

• Save all parameters in a file File [Name].PAR by means of the function Save parameter file of the

FILE menu. This file can then be loaded into the BPCW software by the function Load parameter

file of the FILE menu.

• Leave the BPCW software via the Exit function of the FILE menu.

6.3.4 Amplifier adjustment to a new motor

If the motor used is not in the MOTOR LIST module, proceed as follows:

• Select an amplifier type in the Drive list and the fan type in the module CURRENT.

• Select the amplifier current limitation mode (I

t mode) in the menu CURRENT. The Fusing mode

should be selected for commissioning procedures.

• Check that the value of the Maximum current and Rated current parameters of the CURRENT

module are compatible with the motor and the amplifier. Otherwise, modify them according to the

appropriate motor and amplifier specifications.

• Check that the value of the Max. speed and Accel. Time parameters of the ANALOG INPUT

module are compatible with the motor and the application. Otherwise, modify them according to the

appropriate motor and application specifications.

• Uncouple the motor from the mechanical load and check that the motor shaft is free (one revolution or

more) and that is not dangerous for the operator.

• Select the Software control function of the SETUP menu in the BPCW software version 2.x and

switch on STOP position in the RUN module.
