The
DPTR
command can be used to compare the current pointer location (the number of the data element to
which the data pointer is pointing) against another value or numeric variable, or to assign the pointer location
number to a variable. The current data pointer location is referenced to the current active data program
specified in the first integer of the last
DATSIZ
or
DATPTR
command.
Syntax:
VARn=DPTR
where “
n
” is the variable number,
or
DPTR
can be used in an expression such as
IF(DPTR=1)
Example
:
DATSIZ4,200
; Create data program called DATP4 with 200 data elements
DATPTR4,20,2
; Set the data pointer to data element #20 in DATP4 and set the
; increment to 2 (DATP4 becomes the current active data program)
VAR1=DPTR
; Assign the number of the pointer location in DATP4 to numeric
; variable #1
VAR1
; Response is *VAR1=20. Indicates that the data pointer is
; pointing to data element #20.

power)
Units

Range
0, 8, 16, 20 or 40
Default
0 (use the drive’s default frequency):
GV6K-U3, GV6K-U6, GV6K-U12, GV6K-H20, GV6K-H40: 8 KHz
GV6K-L3: 40 KHz

NOTE
: This command does not take effect until you cycle power to the drive, or issue a
RESET
or
DRESET
command.
Use the
DPWM
command to select the drive’s PWM frequency. This value is the internal PWM frequency as
seen at the motor windings; the motor ripple current is twice this frequency. In general, for a given drive
power level, the higher the switching frequency, the lower the motor ripple current heating and the lower
both the peak and continuous current ratings.
The table below lists the drive’s continuous current and peak current ratings for different PWM
frequencies.
