to another. When the DIGIMAX
entered the first time after power-up, and accelerate to that value. On subsequent restarts,
the ratio will be effective immediately when the RUN is closed. If it is changed while in
operation, the time it takes to change will be proportional to the percentage of the full range
times the parameter #6 value.
This parameter may be changed while in the RUN mode.

#7 DECELERATION TIME

#7 DECELERATION TIME DECELERATION TIME DECELERATION TIME
#7 #7 DECELERATION TIME
For the MASTER mode, enter the desired length of deceleration time (enter in tenths
of seconds) from full speed (as determined by parameter #1) to zero speed. Valid values
are from 0.0 to 999.9 seconds. It will take 1/2 this time to go from full speed to half speed
or from half speed to zero speed. This parameter also sets the rate of decrease in the Motor
Operated Potentiometer mode.
In SLAVE mode, this time affects the time it takes for the ratio to change from one ratio
to another. If the ratio is changed while in operation, the time it takes to change will be
proportional to the percentage of the full range times the parameter #6 value.
This parameter may be changed while the unit is in the RUN mode.

MASTER/SLAVE

MASTER/SLAVE MASTER/SLAVE
#8 #8 MASTER/SLAVE MASTER/SLAVE
Valid values are 0, 1, or 2. See page 32 for more information.
Enter 0 for MASTER mode. In MASTER mode, the DIGIMAX
pulsesbased on the SETPOINT and parameter #5, limited by parameter #1. The frequency,
during ramping periods, is also modified by parameters #6 and #7. The display value is
controlled by parameters #2 and #3. Control from the keypad is ranged by parameter #2.
Enter 1 for SLAVE mode, where direct ratios are entered as SETPOINTs. A reference
frequency must be supplied to TB2 terminals 13(-) and 14(+). The ratio to be entered as a
setpoint is SLAVE/MASTER. The frequency which is generated is determined as a multiple
of the input frequency by parameter #4 and the SETPOINT, and limited by parameter #1.
When the ratio is changed the ramping is controlled by parameters #6 and #7. The ratio will
ramp to a new value, either accelerating or decelerating at the appropriate rate.
Enter 2 for the INVERSE SLAVE mode. This is the same as the SLAVE mode, but
inverse ratios may be entered (i.e.,MASTER/SLAVE instead of SLAVE/MASTER) , as is the
case very often when the lead (or master) motor is after the slave motor in the process. This
makes it unnecessary for the machine operator to calculate ratios of less than 1.0000.
This parameter may not be changed during the RUN mode.

PRESET SPEED

PRESET SPEED PRESET SPEED
#9 #9 PRESET SPEED PRESET SPEED
In the MASTER mode, enter the speed here as you would a SETPOINT. This is the
SETPOINT for the PRESET speed mode. Valid values are from 0 to 99999, but the value
may not exceed parameter #4 (an error code is generated).
In the SLAVE mode, this value is a preset ratio.
This parameter may be changed while running.
#10 #10

JUMP UP CHANGE

JUMP UP CHANGE
#10 #10 JUMP UP CHANGE #10 JUMP UP CHANGE JUMP UP CHANGE
This parameter is an absolute number. Exactly as entered, it will affect the value shown
in the display. Valid values are from 0 to 99999.
Being an absolute value, if the number is 10, the value of the speed or ratio command
will increased by this amount when the UP button is pushed or the UP input is activated. A
speed of 1000 will change to 1010, and a ratio of .4000 will become .4010.
This value is used for the JUMP UP mode and the first step in the MOP UP mode. See
parameter #13 for the explanations of these modes.
This parameter may be changed while running.
