Freq.

: Maximum output frequency value. Refer to the setting in the DPUCONF instruction for the parameter setting.
Alternatively, set the parameter value through HWCONFIG.
: The target frequency specified by the PU module output instruction. The target frequency output must not exceed
the maximum output frequency. If the maximum output frequency is exceeded, the maximum output frequency is
regarded as the output frequency.
: Starting/ending output frequency value. Refer to the setting in the DPUCONF instruction for the parameter setting.
Alternatively, set the parameter value through HWCONFIG.
: The acceleration time value. Refer to the setting in the DPUCONF instruction for the parameter setting.
Alternatively, set the parameter value through HWCONFIG.
: The deceleration time value. Refer to the setting in the DPUCONF instruction for the parameter setting.
Alternatively, set the parameter value through HWCONFIG.
The acceleration and deceleration that the PU module controls is performed according to the fixed slope. So the
actual acceleration time and deceleration time change based on the output target frequency. The formula for
calculation of acceleration rate and deceleration rate are respectively shown as follows.
(Max. output frequency - starting frequency)/acceleration time;
(Max. output frequency - ending frequency)/deceleration time.
Programming Example:
1. Configure parameters of AS02PU module in HWCONFIG. Set "Axis 1, DOG, Rising-edge triggered" for input point
X0.0, "Axis 1, Z phase, Rising-edge triggered" for input point X0.1 and "Phase A Y0.0+ Phase B Y0.1" for output point.
Other parameters of axis 1 are set as default.
