7.
Read the sensor signal on the
SENSOR MONITOR
SMB socket using the voltmeter.
8.
Adjust the
Zero
potentiometer using the trimmer adjustment tool until the sensor
signal is +1 V.
Performing the Zero-Point Adjustment in Computer-Controlled Mode (only E-625.CR)
1.
Select the computer-controlled mode and the open-loop operation (servo mode OFF)
using the
Settings
DIP switch block:
−
1: OFF (up)
−
2: ON (down)
−
3: OFF (up)
−
4: ON (down)
2.
Optional: Connect the voltmeter to the
SENSOR MONITOR
SMB socket using the
adapter cable.
3.
Connect the power cord on the wide input range power supply to the power socket.
The E-625 is ready for operation when the green
Power
LED comes on.
4.
Establish communication between the PC and the E-625, e.g., with PIMikroMove.
5.
Send the
SVO A 0
command (
A
indicates the axis) to ensure that servo mode is
switched off.
6.
Increase the piezo voltage using the SVA command in increments of 10 volts from 0 V
up to the value where the upper travel range limit for the positioner is reached
approximately.
7.
Send the
SVA A 0
command to set the piezo voltage to 0 V (
A
indicates the axis).
8.
Read the sensor signal.
−
Use the voltmeter on the
SENSOR MONITOR
SMB socket.
or
−
Send the
POS? A
command (
A
indicates the axis).
9.
Adjust the
Zero
potentiometer using the trimmer adjustment tool until the sensor
shows 10 % of the travel range:
−
The voltmeter on the
SENSOR MONITOR
SMB socket shows +1 V.
or
−
The response to the
POS? A
command is approx. 10 % of the travel range (in µm).
Was the Zero-Point Adjustment Successful?
After the successful zero-point adjustment, the overflow LED will no longer light up in
closed-loop operation. When the overflow LED light is on constantly in spite of the zero-point
adjustment, there can be a hardware error.
