command 'rk'
call: rk,<ch>
answer: rk,<ch>,<value>
The command „rk" reads out either the position value for one channel <ch> from the
measuring system in closed loop () or the voltage applied to the actuator in open loop. The
readout value is given with 3 decimal places.
command 'measure'
call: measure
answer: aw,<value0>,<value1>,<value2>
The command „measure" reads out either the position <value0, 1, 2> from the measuring
system in closed loop () or the voltage applied to the actuator in open loop. The readout
values <value0, 1, 2> are given with 3 decimal places.
command 'monwpa'
call: monwpa,<ch>,<0|1|2>
answer: none
modes: 0 =
1 =
2 =
Command without value reads out the current value.
command 'ver'
call: ver
answer: version,vnumber,vdate
This command "ver" reads out the software version number of the internal controller, the date
and the serial number of the amplifier.
command 'ERR?'
call: ERR?
answer: ERROR,<"last error">
The command "ERR?" gives the last failure from the controller. After read out the error from
the controller the failure status in the memory will be deleted. The output of the error
message occurs as plain text.
command 'fready'
call: fready,<0|1>
answer: none
This command 'fready' enables the soft start function for all channels. After switching on the
system the soft start function is started for 10 seconds to initiate the actuator. While this
routine the actuator is moved once through the whole motion range and back. During soft

always voltage to the position of the piezo actuating system ()
ol = actuator voltage, cl = measuring system voltage ()
example: rk,1
