4.2MASTER MODE SETUP

1.SET PARAMETER #5 FOR THE MASTER MODE.

Set the basic operation in this parameter to

MASTER.

This parameter also has options for current control (see page 16). Selecting MASTER into the parameter takes care of the normal MASTER mode operation case because the default is normal current limits.

Other choices are torque limiting (either motoring or regenerative) and horsepower control. If one of these choices is made, it will be necessary to either:

1.Set up one analog input for a reference (see INPUTS and OUTPUTS), or

2.Make provision to supply reference through communications (see page 16).

2.SET PARAMETER #17 OR PARAMETER #21

IF AN ANALOG INPUT IS TO BE USED.

If an analog speed reference is to be used, either Analog Input #1 (see page 20) or Analog Input #2 (see page 22) must be set to Speed Reference Input. By default, Analog Input #1 is set up as a Speed Reference Input and Analog Input #2 is a General Purpose Input.

You must also set parameter #18 (0 to 10VDC by default) or parameter #22 (4 to 20 milliamps default) for the type of input. Then set up the scaling (Engineering units) in parameters #19 and #20 for Analog Input #1, or parameters #22 and #23 for Analog Input #2.

If neither analog input is set up as a speed reference, then the speed reference must be supplied from the optional front panel control or from the communications.

3.SET PARAMETER #8 FOR THE MASTER ACCELERATION RATE.

Set the master speed acceleration time in milliseconds (1 millisecond = .001 second). The range is from 0 (speed changes are step functions) to 255 seconds.

4.SET PARAMETER #9 FOR THE MASTER DECELERATION RATE.

Set the master speed deceleration time in milliseconds (1 millisecond = .001 second). The range is from 0 (speed changes are step functions) to 255 seconds.

5.SET PARAMETER #12 FOR A MASTER PRESET SPEED.

This step is optional, if you wish to use a preset speed which can be toggled by the PRESET function. Enter the speed in Engineering Units.

6.SET PARAMETER #54 FOR SETPOINT CONDITION (FLOAT OR FREEZE) AT START-UP.

If you want the motor to return to the speed at which it was running prior to shutdown or power loss, set this parameter to Freeze.

If you want the motor to wait for the speed to be reentered after a stop or power loss, enter Float in this parameter. See page 30.

7.SET PARAMETER #48 FOR JUMP OR MOP MODE.

Jump mode operation is to make UP/DOWN speed changes temporary. MOP mode makes the DFS-1 act like a Motor Operated Potentiometer. See page 28.

8.SET PARAMETER #49 FOR MASTER JUMP UP AMOUNT.

This is the amount (in Engineering Units) by which the speed command will increase when the UP function is activated. See page 29.

9.SET PARAMETER #50 FOR MASTER JUMP DOWN AMOUNT.

This is the amount (in Engineering Units) by which the speed command will decrease when the DOWN function is activated. See page 29.
