4.3SLAVE MODE SETUP
1.SET PARAMETER #5 FOR THE SLAVE MODE.
Set basic operation in this parameter to 1 for SLAVE mode. For INVERSE SLAVE mode enter 2. INVERSE SLAVE mode affects the way a setpoint is entered.
This parameter also has options for current control (see page 16). Setting a 1 takes care of the normal SLAVE mode because the default is normal current limits.
Other choices are torque limiting (either motoring or regenerative) and horsepower control. For these options 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 followed in SLAVE mode, either Analog Input #1 (see page 20) or Analog Input #2 (see page 22) must be set to 1 (Speed Reference Input). By default, Analog Input #1 is set up as a Speed Reference Input.
You must also set parameter #18 (0 to 10VDC by default) or parameter #22 for the type of input. Then set up the scaling parameters #19 and #20, or #22 and #23.
If neither analog input is set up as a speed reference input, then the speed reference to be followed must be supplied from the Frequency Reference In.
3.SET PARAMETER #15 FOR THE BASE RATIO.
This is the number which is used to allow the SETPOINT to be set at a desired number instead of at a number dictated by gear ratios, motor speeds, and other factors. See page 19.
4.SET PARAMETER #16 FOR THE MAXIMUM RATIO.
This setting is the highest ratio allowed under any circumstances.
5.SET PARAMETER #55 FOR THE MINIMUM RATIO.
This setting is the smallest ratio allowed under any circumstances.
6.SET PARAMETER #10 FOR THE SLAVE ACCELERATION RATE.
Set slave speed acceleration time in milliseconds (1 millisecond = .001 second). The range is from 0 (speed changes are step functions) to 255 seconds. See page 18.
7.SET PARAMETER #11 FOR THE SLAVE DECELERATION RATE.
Set the slave speed deceleration time in milliseconds (1 millisecond = .001 sec). The range is from 0 (speed changes are step functions) to 255 seconds. See page 18.
8.SET PARAMETER #13 FOR A SLAVE PRESET RATIO.
This step is optional, if you wish to use a preset ratio which can be toggled by the PRESET function. Enter the speed in Engineering Units.
9.SET PARAMETER #54 FOR SETPOINT CONDITION AT START-UP.
If you want the motor to return to the ratio at which it was running prior to shutdown or power loss, set this parameter to 1. If you want the motor to wait for the ratio to be reentered after a stop or power loss, enter 0. See page 30.
10.SET PARAMETER #48 FOR JUMP OR MOP MODE.
Jump mode operation is to make UP/DOWN ratio changes temporary. MOP mode makes the
11.SET PARAMETERS #51 AND #52 FOR SLAVE JUMP UP/DOWN AMOUNTS.
These are the amounts (in Engineering Units) by which the ratio command will increase or decrease when the UP or DOWN functions are activated. See page 29.
