The component speed (initial speed and maximum speed of
each axis) is stored as 2 words in real type.

Example) Even when the initial speed is corrected, the
calculated value is stored as is in the operation result storage

Frequency range
The frequency ranges are automatically selected by the system
for the components of each axis.
0: Low speed range (1 Hz to 22 kHz)
1: High speed range (50Hz to 100 kHz)
When the initial speed (X/Y axis) is the low speed range and the
maximum speed (X/Y axis) exceeds 22 kHz, the initial speed
(X/Y axis) is corrected to 50 Hz.
When the initial speed (X/Y axis) is less than 1 and the
maximum speed (X/Y axis) exceeds 22 kHz or less, the initial
speed (X/Y axis) is corrected to 1 Hz.

Acceleration/deceleration
steps
The acceleration/deceleration steps are automatically calculated
by the system in the range of 0 to 60 steps.
・
When the operation result is 0, the pulse output is
performed at the initial speed (composite speed) without
acceleration and deceleration.
・
The acceleration/deceleration steps are calculated by the
following formula; Acceleration/deceleration time (ms) x
Initial component speed (Hz).
Example) When the settings are as follows; Incremental, Initial
speed=5 kHz, Acceleration/deceleration time=0.5 s, CH0 target
value=1000, and CH2 target value=50.

 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 is considered.)
