S+8, S+9
Deviation counter
clear signal output
time
tr(ms)
Set the output time of the deviation counter clear signal.
0.5 ms to 100 ms [K0 to K100] Setting value + error (0.5 ms or
less)
When this signal is not used or the time is set to less than 0.5 ms,
specify K0.

 Regarding the specification of acceleration/deceleration time
For specifying acceleration/deceleration time, No. of steps and initial speed, set the value to
be calculated by the formula below. Specify acceleration/deceleration time in 30 ms
increments with 30 steps, and in 60 ms increments with 60 steps. When the time is not
specified in 30 ms nor 60 ms increments, it will be automatically corrected to the multiple
values (larger value) of 30 ms or 60 ms.
Acceleration/deceleration time t[ms] ≥ (No. of steps x 1000)/Initial speed f0[Hz]
• When "Acceleration/deceleration time priority" is specified for the control code, the initial
speed is corrected according to the time.
The corrected speed is stored in the correction speed area of initial speed of special data
registers (from DT90400).
(Example): When the initial speed is 10 Hz, and acceleration/deceleration time is 1 msec,
the initial speed is corrected to 1000 Hz.
• When the corrected initial speed exceeds the maximum speed, the initial speed is corrected
to the maximum speed.
(Example): When the initial speed is 10 Hz, the maximum speed is 500 Hz,
acceleration/deceleration time is 1 msec, and acceleration/deceleration time priority is
specified, it takes 100 msec for outputting one pulse at the initial speed and it exceeds 1
msec of acceleration/deceleration time.
Although the initial speed is corrected to 1000 Hz as "Acceleration/deceleration time priority"
is specified, it is corrected to 500 Hz because it exceeds the maximum speed.
 Supplement to pulse output operation
When outputting pulses with the PLS+SIGN (direction output) method, pulses will be output
approx. 300µs later after the output of direction signal (SIGN). (The characteristics of a motor
driver are considered.)
