6.4 Pulse Output Function
6.4.1 Overview of Pulse Output Function
Instructions used and controls
Together with a commercially available pulse-string input type motor driver, the pulse output function can
be used for positioning control.
Type of control
Exclusive
instru-
ction
Description Usable unit
Trapezoidal control
Provides trapezoidal (table-shaped)
control for automatically obtaining
pulse outputs by specifying the initial
speed, maximum speed,
acceleration/deceleration time and
target value.
Home return
F171
(SPDH)
Enables automatic home return
operation.
JOG operation
F172
(PLSH)
Causes pulses to be output as long
as the execution condition is on. A
target value can also be set, so that
pulse output stops at the point when
the target value is matched.
Data table control
F174
(SP0H)
Enables positioning control in
accordance with the data table.
C32T
C32T2
C28P2
C32TH
C32T2H
C28P2H
Linear interpolation
F175
(SPSH)
Enables pulses to be output using
linear interpolation control, by
specifying the composite speed, the
acceleration/deceleration time, and
the target value.
Circular interpolation
F176
(SPCH)
The user can select one of two
circular forming methods, one by
specifying the pass positions and the
other by specifying a center position.
Pulses are output using circular
interpolation control, by specifying the
various parameters.
C32T2
C28P2
C32T2H
C28P2H
Note:
• The thermister input type for various units is included.
• The pulse output function can be used with the transistor output type only.
Setting the system register
When using the pulse output function, set the channels corresponding to system registers 400 and 401
to “Do not use high-speed counter”.
