2.23 SPEED COINCIDENCE
Cn-21: Speed Coincidence Frequency Factory setting: 0.0 Hz
Range: 0.0 to 400.0 Hz
Cn-22: Speed Coincidence Bandwidth Factory setting: 2.0 Hz
Range: 0.0 to 25.5 Hz
Speed coincidence is used to control an output contact at terminals 9 & 10, or one of the
open collector outputs at terminals 25 & 26 (with respect to terminal 27), when selected
by Sn-20 thru Sn-24.
Sn-20: Multi-function Output 1 – Contact Data 02 , 03 , 04 or 05
(terminals 9 & 10) (See paragraph 2.21,
Sn-21: Multi-function Output 2 – Open Collector MULTI-FUNCTION
(terminals 25 & 27) OUTPUT TERMINALS
Sn-22: Multi-function Output 3 – Open Collector (Term. 9 & 10; 25-27) )
(terminals 26 & 27)
The output contact will close, or the open collector output will go low, when acceleration or
deceleration is completed, and output frequency is within the detection width shown in the
figure below.
EXAMPLE:
If Cn-21 = 20 Hz, Cn-22 = 15.0 Hz and Sn-20 = 03 , then the contact at
terminals 9 & 10 will be closed from 25 Hz to 35 Hz.
