(13)Origin Drive Direction Changing Function
The precondition for origin drive is that the ORG (or NORG) sensor has been installed at the -(CCW)
limit side along works, but the origin drive direction changing function enables to install the ORG
(or NORG) sensor on the +(CW) limit side.
(14)Margin Time Function
In order to prevent the origin drive from malfunctioning due to hunting, this function enables to insert
a margin time between the sensor signal detection and the pulse stop.
(15)SOFT LIMIT Function
This function allows you to set up CW or CCW SOFT LIMIT.
(16)DEND ERROR Detection Function
If active level of DEND signal is not returned during the predetermined time span, this function ends the
drive forcibly by setting 1 to the error bit of STATUS1 PORT.
(17)Origin Sensor Type Select Function
This function allows you to switch the ORG sensor detection approach from the edge sensing to the level
sensing.
(18)ORIGIN ERROR Detection Function
Specifying the maximum number of pulses to be output during the CONSTANT SCAN DRIVE process and JOG DRIVE
process, this function can end the drive forcibly if the sensor fails to make detection during that range
of pulse number.
(19)PO Input Function
This function offers origin detection utilizing PO (excitation) output signal from stepping motor drivers.
When PO input is enabled, ANDing of PO signal and ORG signal is output as ORG signal.
(20)AUTO DRST Output Function
This function automatically outputs DRST signal as the machine origin detection completed.
(21)Special DRST Output Function
This function allows you to constantly generate DRST output.
(22) Asymmetric S-RATE DRIVE function
Acceleration/deceleration constant can be set separately in the S-shaped DRIVE.
(23) S-RATE DRIVE triangular drive workaround function
The DRIVE profile is rounded automatically when there are few output pulses in the S-shaped
DRIVE, thereby working around the triangular drive. It should be noted, however, that this
is disabled in the asymmetric S-RATE DRIVE.
(24) SPEED/RATE CHANGE speed increase function
The operation from the writing of CHANGE command is performed on the real time basis
in the SCAN DRIVE.
(25) AUTO CHANGE function
The SPEED and RATE are changed automatically according to the preset number of output
pulses, speed or time.
(26) DRIVE calculation function
The number of acceleration pulses, acceleration time and INDEX DRIVE drive time can be
obtained by simulated calculation.
