CHECKLIST BEFORE COMMISSIONING
To facilitate commissioning, please check the following items in advance:
0
The pulse rate of the encoder must be set correctly on the encoder, 400 pulses per
spindle revolution are usually optimal.
0
This pulse rate must also be adopted in the settings of the ELS (SETTINGS -> SETUP
ENCODER -> IMPULSES/REV).
0
The stepper or servo motors must be wired correctly to the output stages, see the data
sheets and connection diagrams on the previous pages.
0
The motordrivers must be connected to the appropriate power supply.
0
The following settings must be made on the motordrivers of the step servo motors:
0
a)
Adjust the current to suit the motor
0
b)
Set step rate, 400, 800 or 1600 steps
0
The step rate of the motordrivers must also be entered for the X and Z axes in the
settings of the ELS!
0
For both axes the parameters for step rate, acceleration and slow and fast movement
must be entered. For acceleration, first start with 50, slow and fast travel with 300 mm/
min or 1500 mm/min.
0
Set the pitch of the threaded spindles on the Z and X axes.
(SETTINGS -> SETUP Z/X MOTOR -> SPINDLE PITCH)
Very important:
•
Set the encoder pulse rate on the encoder AND in the settings of the ELS.
•
Set the step rate of the stepper motors on the motordrivers AND in the settings of
the ELS.
•
Setting the thread spindle pitches
Then carry out the commissioning as described below, quick version:
1. Press the Z-axis JOG button and see if the axis is moving in the right direction. If the axis
moves in the wrong direction, change the direction of rotation in the settings. This can be
done separately for both axes (under SETTINGS -> Z MOTOR -> REVERSE DIRECTION).
2.
Do the same for the X-Axis.
3. If the axes are moving correctly, switch to GEARBOX LEFT.
4.
Switch on the spindle slowly and press the START button. Now the carriage should move to
the left when the spindle rotates counterclockwise. If the slide moves in the wrong direction,
go to the settings and change the direction of rotation of the incremental encoder (under
SETTINGS -> SETUP ENCODER -> REVERSE DIRECTION).
