Only if the housing needs to be opened for the adjustment of internal settings:
−
Phillips-head screwdriver, size PH1
−
Trimmer adjustment tool
Performing a System Test in Analog Mode
1.
Select analog mode and open-loop operation (servo mode OFF) using the
Settings
DIP
switch block:
−
1: ON (down)
−
2: OFF (up)
−
3: OFF (up)
−
4: OFF (up)
2.
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.
3.
Determine the resonant frequency of the positioner:
a)
Connect the function generator to the
ANALOG IN/WTT
SMB socket using an
adapter cable.
b)
Connect the oscilloscope to the
SENSOR MONITOR
SMB socket using an adapter
cable.
c)
Generate a 1-V square wave signal (peak-peak) with 2 to 5 Hz using the function
generator.
d)
On the oscilloscope (Y-t or FFT diagram), read the resonant frequency of the
positioner.
If the resonant frequency is not dampened sufficiently (peak too high):
e)
Open the E-625 (p. 36).
f)
Adjust (p. 43) the notch filter accordingly on the E-802 servo controller submodule.
4.
Determine the position of the positioner at 0 V input voltage:
a)
Remove the oscilloscope from the
SENSOR MONITOR
SMB socket.
b)
Connect the voltmeter to the
SENSOR MONITOR
SMB socket using the adapter
cable.
c)
Use the function generator (DC mode) to increase the input voltage on the
ANALOG
IN/WTT
SMB socket in increments of 1 volt from 0 V up to the value where the
upper travel range limit of the positioner is reached approximately.
d)
Reduce the input voltage on the
ANALOG IN/WTT
SMB socket to 0 V.
e)
Read the sensor signal on the
SENSOR MONITOR
SMB socket using the voltmeter.
If, with 0 V input voltage, the sensor monitor signal is larger than +1 V (+1 V
corresponds to 10 % of the travel range):
f)
Adjust (p. 27) the zero point of the sensor.
