POINT
(1) When changing the ring counter upper/lower limit value, perform the following:
• Turn OFF the count enable command (Y04) for 2ms or longer.
• Change the setting of the ring counter upper limit value (Un\G2 and 3)
and/or ring counter lower limit value (Un\G0 and 1).
• Turn ON the count enable command (Y04) again.
While the count enable command (Y04) is ON, writing a setting value into the ring
counter upper/lower limit value area (Un\G0 to 3) only stores it in the buffer
memory and is not reflected to the QD63P6. Therefore, the QD63P6 operates
based on the setting before the writing.
If a value was written to the ring counter lower limit value (Un\G2 and 3) or ring
counter upper limit value (Un\G0 and 1) with the count enable command (Y04) set
to ON, turn OFF the count enable command (Y04) for 2ms or longer and then
back ON again. The set value becomes effective in the QD63P6 by this
operation.
(2) When changing the count range by preset, to prevent a miscount, be sure to
turn OFF the count enable command (Y04).
