0x07012700 1 PiezoWalk
Channel
FLOAT Time To Close Brake Time to close the brake assigned to a
PiezoWalk channel, in s
To close the brake, for the assigned
output signal channel first the lower limit
for the piezo voltage output is set, and
afterwards the zero voltage value.
0x07012800 1 PiezoWalk
Channel
FLOAT Time To Relax
PiezoWalk Channel
[s]
Duration of the simple relax procedure
for PiezoWalk® drives
If the parameter value is zero (default
setting), the duration depends on the
setting of the PiezoWalk Open-Loop
Velocity parameter (0x07000204).
See p. 12 for further details.
0x07012900 1 PiezoWalk
Channel
FLOAT Anti Creep First
Voltage
Creep reduction procedure for the piezo
actuators of a NEXLINE® drive. If
activated, the creep reduction procedure
is executed immediately after the
iterative relax procedure.
See p. 15 for further details.
