7.4. SMB modulation input: MOD
The motion of the actuator may be remotely controlled by using this input. The
control signal must be in the range of 0 ... +10V. There is an internal addition
of the MOD signal and the adjusted OFFSET potentiometer. If there is an
HIGH TTL level at the Pin8 of the rear panel connector, OFFSET and MOD
(modulation input) are switched off. The remote control via Pin7 of the rear
panel connector is active and possible.
7.5. SMB monitor output socket: MON
12V40:
The output voltage in ratio 10:1 (-1 ... +15V) is available at this socket and can
be monitored by using an analogue oscilloscope. This is especially
recommended for dynamical operation. Pay attention to the inner resistance
of the monitor output, only high ohmic measurement devices (>100k
Ω) should
be used. The output is short protected, please avoid injected voltages.
12V40SG / 12V40CLE:
The measuring voltage (0…10V) is available at this socket and can be
monitored by using an analogue oscilloscope. This is especially
recommended for dynamical operation. Pay attention to the inner resistance
of the monitor output, only high ohmic measurement (>100k
Ω) devices should
be used. The output is short protected, please avoid injected voltages.
7.6. Actuator socket: OUT
Please connect the actuator by using this socket.
7.7. Switch closed loop (12V40SG / 12V40CLE)
Using this switch the closed loop operation can be turned on. The amplifier
12V40SG includes an electronic closed-loop and a strain gauge measurement
system. The 12V40CLE uses a measuring system which is combined with the
actuator. This allows to compensate drift and hysteresis of the piezo actuator.
Please take care of settling time when using in dynamic operation.
