The Servo Control requires a single 115V AC supply. To turn on your Servo Control:

1. Press 0 on the rear panel Power switch to make sure that the Servo Control power is off.
2. Connect the control cables (MOTOR/BRAKE and ENCODER) from the table/indexer.
3. Connect the remote input (CNC Interface) cable from the mill (and/or the RS-232 UP cable from the PC or CNC Mill).
4. Connect the Servo Control power cord to a 120VAC, single-phase, 50/60 Hz power supply. Press 1 on the rear panel Power switch to power on the Servo Control.
5. The Servo Control runs a self-test and then displays: To begin Clear Alarms then Press Cycle Start. If the display gives an alarm message, refer to the Alarm:Error Codes section of this manual, starting on page 5. The numbers remain in the display for only about one second. The Por On message indicates that the motors are turned off. This is normal.
6. Pull the Emergency Stop to disengage it, if it is set. Press a key to continue operation.

When the Servo Control is first turned on, it is in Run mode but the servo motor is turned off. This is indicated by: Por On. Pressing CYCLE START allows you to continue operation.

Run mode is used to execute pre-programmed commands. The servo loop can be turned on in this mode and holds the motor to a commanded position when idle.

When an area of the display is flashing on and off, you are in Program mode. To return to Run mode:

Press and release MODE/RUN PROG until the display is steady.

After turning on the Servo Control, you may need to initialize the control to your rotary model. To initialize the servo control:

1. Go to parameter mode. Press MODE/RUN PROG.
   The display flashes.
   
   
2. Press and hold STEP SCAN up arrow for 5 seconds.
   The display is in parameter mode.
   
   
3. Press and hold CLEAR/ZERO SET for 5 seconds.The display shows a rotary model.
   
   
4. Press DISPLAY SCAN to scroll to find model type.Press CYCLE START.
   
   
5. Press STEP SCAN to model version.
   
   
6. Press CYCLE START.  The display shows Detecting Motor, and parameters begin loading for your model rotary.
   
   
7. When parameter loading stops, press MODE/RUN PROG.
   
   
8. Power off and on the Servo Control.
9. Press the front panel CYCLE START switch once.
   
   The display shows 01 no Ho. This means that the motor(s) are now powered but zero position is not defined (there is no home position).

To jog the rotary unit:

Select the jog rate as a percent of the maximum feed rate with the front panel number keys. For example, press 5 and then 0 to select 50 percent jog rate.

Press JOG + or - to move the table at the jog rate you selected to the position that you want.

If the control is set up for linear motion; there are both positive and negative travel limits possible. If a step exceeds the travel limits, the control gives the message 2 FAr and the step is not executed.

Parameters 13 and 14 control the maximum travel distances. Information about these parameters go to the parameter section.

To turn off the servo, cause the spindle to decelerate and stop, and display E-STOP:

Press EMERGENCY STOP on the Servo Control.

If the last step was not completed, the control remains on that step so the rotary position is not lost.

To restart, pull out the EMERGENCY STOP button and push CYCLE START twice (once to turn the servo on, and again to restart the step).

The remote CYCLE START and FINISH SIGNAL will not function until you pull out the EMERGENCY STOP button and push CYCLE START.

The illustrations in this section show the layout of the A and B axes in the Haas five-axis control. The A Axis is rotary motion around the X Axis, while the B Axis is rotary motion about the Y Axis.

You can use the right-hand rule to determine axis rotation for the A and B axes. Place the thumb of your right hand along the positive X Axis. The fingers of your right hand point in the direction of tool movement for a positive A-Axis command.

Likewise, with the A Axis at 90°, if you place the thumb of your right hand along the positive Y Axis, the fingers of your hand point in the direction of tool movement for a positive B-Axis command.

It is important to remember that the right-hand rule determines direction of tool movement, and not the table movement direction. For the right-hand rule, the fingers point opposite of the positive rotary table movement. Refer to these figures.

NOTE: These illustrations are representative only. Different table movements are possible for positive directions, depending on the equipment, parameter settings, or the five-axis programming software you use.

To find the zero position automatically:

Press ZERO RETURN to start the automatic homing operation.

When the table/indexer stops, the display indicates: 01 Pnnn.nnn.

If the display shows a non-zero number, press CLEAR/ZERO SET for three seconds.

To manually find the zero position:

Use JOG + or - to move the table to the position that you want to use as zero.

Press and hold CLEAR/ZERO SET for three seconds.

The display should now indicate: 01 P 000.000. This indicates that the zero position is established and the controller is ready to begin normal operations.

If the new home position is cleared, the display shows a non-zero position. In this case, press ZERO RETURN and the table moves to the pre-defined zero position.

To offset the Zero Position:

Use JOG + or - to move the rotary unit to the position to use as zero and press CLEAR/ZERO SET for 3 seconds.

The following is displayed: 01 P000.000.

If there is a zero offset defined, a non-zero number is displayed. In this case, press ZERO RETURN once and the unit moves forward to the predefined zero position.

Here are a few servo control operating hints:

To select another display while in the Run mode, press DISPLAY SCAN.

A program can be started at any step by pressing STEP SCAN up or down.

Make sure the mill has the same number of M-Codes programmed as steps in the rotary control.

Do not program two consecutive M-Codes in the mill to index the rotary control. To avoid a timing fault in the mill, use a dwell of 1/4 second between M-Codes.

For all rotary units, the default values are:

If an entry is cleared or set to 0 by the operator, the value is changed by the control to the default value. All entries are stored when selecting the next display function, step number, or returning to Run mode.
