 Selecting the fast-response operation (Pr.800 = "109 or 110")
• Setting Pr.800 = "109 or 110" selects the fast-response operation. Fast-response operation is available during PM motor
control.
Control method
PM motor control
NOTE
• Refer to page 179
• During fast-response operation, E.THT is likely to occur.
 I/O signal operation during the test operation
• During the test operation, the following signals are invalid.
 Input terminal function selection (Pr.178 to Pr.189)
• V/F switchover signal (X18)
• Start-time tuning start external input signal (X28)
 Output terminal function selection (Pr.190 to Pr.196)
• Electronic thermal O/L relay pre-alarm signal (THP)
• Start time tuning completion signal (Y39)
