Brakeoperationselectionforvectorcontrol(Pr.1299)
• The brake operation of the second motor can be selected under vector control or PM sensorless vector control.
Turning ON the RT signal enables the second pre-excitation selection (when Pr.450  "9999").
NOTE
• For the details of the pre-excitation operation, refer to page 609 of the Instruction Manual (Detailed).
Position loop gain (Pr.1298)
• The position loop gain can be set for the second motor under vector control or PM sensorless vector control.
Turning ON the RT signal validates the second position loop gain (when Pr.450  "9999").
NOTE
• For the details of the position loop gain, refer to page 251 of the Instruction Manual (Detailed).
Pulse monitor selection (Pr.430)
• The current position 2 can be selected for the pulse monitor selection.
 Accumulated value of estimated feedback pulses when PM sensorless vector control is used
• The following can be monitored with the PLC function special register.
