(23) Frequency Agree Detection Level During Acceleration (Cn-29)
(24) Frequency Agree Detection Level During Deceleration (Cn-30)
(25) Frequency Agree Detection Width (Cn-31)
•Frequency detection function: Set the multi-function output terminals (control
circuit terminals RA-RB-RC or R1A-R1B-R1C, DO1, DO2 or R2A-R2C) to
output the desired Frequency Agree signal, Setting Frequency Agree and Output
Frequency Detection level (through proper setting of Sn-30 ~ Sn-32).
•The time chart for Frequency Detection operation is described as follows:

When output freq. is within freq.
command +/- freq. Detection width
(Cn-31), frequency agree output is
“ON”.
•
Set Sn-30
∼
Sn-32 to be “02” for the
setting of frequency agree output.
