Revised 7/95 DFS-1 Manual
POWERTEC Ind. Corp.©
When parameter #48 is set to 0000 0000h, the
DFS-1 is in the JUMP mode. In MASTER mode (set
by parameter #5), when the UP input function is
activated, the speed will increase by the amount set
in parameter #49. As long as the UP function is
active, the speed change will be held. When the UP
function is released the speed returns to the SET-
POINT. The same action applies to the DOWN
function, the speed change set by parameter #50. In
SLAVE mode, there is a temporary change in ratio
determined by parameter #51 for UP and #52 for
DOWN.
When parameter #48 is set to 0000 0001h, the
DFS-1 is in the MOP mode. The MOP mode acts like
a Motor Operated Potentiometer. When the UP
function is activated, the speed, in MASTER mode,
will change immediately by the amount in parameter
#49. If the function is released within 1/2 second, that
speed becomes the new SETPOINT. If the UP
function is held for more than 1/2 second, the speed
will begin to increase at the ACCEL rate (determined
by parameter #8), increasing until the UP function is
released. After the UP function is released, the speed
will remain at the latest, which becomes the new
SETPOINT. The same action applies in the MAS-
TER mode to the DOWN function (with parameter
#50 and the DECEL rate in parameter #9). In SLAVE
mode, the immediate increase is set by parameter
#51, the immediate decrease by parameter #52, and
the rates by parameters #10 and #11, respectively.
49. MASTER JUMP UP AMOUNT
USE PARAMETER #49 TO SET THE AMOUNT
OF SPEED CHANGE ON AN UP FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 869Fh
0 to 99,999 (decimal)
Default Value: 0000 0001h 1 (decimal)
Parameter #49 is the amount, in Engineering
Units, by which the speed changes when the UP
function is active.
50. MASTER JUMP DOWN
AMOUNT
USE PARAMETER #50 TO SET THE AMOUNT
OF SPEED CHANGE ON A DOWN FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 869Fh
0 to 99,999 (decimal)
Default Value: 0000 0001h 1 (decimal)
Parameter #50 is the amount, in Engineering
Units, by which the speed changes when the DOWN
function is active.
51. SLAVE JUMP UP AMOUNT
USE PARAMETER #51 TO SET THE AMOUNT
OF RATIO CHANGE ON AN UP FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 869Fh
0 to 99,999 (decimal)
Default Value: 0000 0001h 1 (decimal)
Parameter #51 is the amount, in Engineering
Units, by which the ratio changes when the UP
function is active.
52. SLAVE JUMP DOWN
AMOUNT
USE PARAMETER #52 TO SET THE AMOUNT
OF RATIO CHANGE ON A DOWN FUNCTION.
RANGE OF VALUES: 0000 0000h to 0001 869Fh
0 to 99,999 (decimal)
Default Value: 0000 0001h 1 (decimal)
Parameter #52 is the amount, in Engineering
Units, by which the ratio changes when the DOWN
function is active.
