speed measurement) (Un\G1151), and CH1 Number of pulses per rotation (Un\G1152, Un\G1153). (The change of the
setting values during the rotation speed measurement is ignored.)
• Reset CH1 Measured rotation speed value update flag (Un\G1181) to 0
H
: Not updated.

The following operation is performed when the measured value of the rotation speed is stored in CH1 Measured rotation speed
value (Un\G1182, Un\G1183):
•1
H
: Updated is stored in CH1 Measured rotation speed value update flag (Un\G1181).
3)
Reset CH1 Measured rotation speed value update flag (Un\G1181) to 0

: Not updated by setting CH1 Measured rotation speed
value update flag reset command (Un\G1170) to 1
H
: Reset.
CH1 Measured rotation speed value update flag reset command (Un\G1170) is automatically reset to 0
H
: Not reset after the
completion of the reset.
4)

H
: Updated is stored in CH1 Measured rotation
speed value update flag (Un\G1181).
5)
0
H
: Not operating is stored in CH1 Rotation speed measurement flag (Un\G1180) by turning off CH1 Count enable command
