Description
Notes
Open-Loop Velocity parameter (ID
0x07000204); in closed-loop operation by
the VEL command (which concerns the
Servo Loop Slew-Rate parameter, ID
0x07000200).
0x07011b00 1 PiezoWalk
Channel
FLOAT PiezoWalk Max
Acceleration
[µm/s
2
]
Maximum acceleration of a PiezoWalk®
drive.
0x07011d00 1 PiezoWalk
Channel
INT PiezoWalk Type 1 = NEXLINE
2 = NEXACT (also required for
PICMAWalk)
0x07011e00 1 PiezoWalk
Channel
FLOAT NEXACT Drive Weight Gives the ratio of the shearing voltage
amplitude to the clamping voltage
amplitude. This ratio influences the feed
caused by one step cycle, i.e. the step
size.
Only used if PiezoWalk Type (ID
0x07011d00) = 2 (NEXACT, PICMAWalk).
0x07011f00 2 PiezoWalk
Channel
INT PiezoWalk Driven
Cycles
Counter for the electrical cycles
performed by a PiezoWalk drive.
0x07012400 2 PiezoWalk

INT To PiezoWalk Linked
Sensor Chan
Gives the ID of an input signal channel
with limit switches that is assigned to the
PiezoWalk channel.
0 (default) = no channel assigned
0x07012500 1 PiezoWalk
Channel
INT To PiezoWalk Linked
Brake Output Chan
Gives the ID of an output signal channel
with brake that is assigned to the
PiezoWalk channel. The brake of the
assigned output signal channel is open as
long as the PiezoWalk channel is not in
the relaxed state (opened when the servo
mode is switched on, closed when the
servo mode is switched off).
0 (default) = no channel assigned
0x07012600 1 PiezoWalk
Channel
FLOAT Time To Open Brake Time to open the brake assigned to a
PiezoWalk channel, in s
To open the brake, for the assigned
output signal channel first the lower limit
for the piezo voltage output is set, and
afterwards the upper limit.
