SMOTIME (P58)
Sometimes the axis does not respond as desired on particular movements (handwheel movements,
etc.).
In these cases, the axis response may be smoothed by applying a filter to speed variations. This
filter is set by parameter SMOTIME that indicates the duration of the filter in milliseconds, value given
by g.m.p. LOOPTIME (P72).
To obtain a better response, parameter SMOTIME of the axes interpolating with each other should
be set with the same value.
ACCTIME2 (P59) PROGAIN2 (P60) DERGAIN2 (P61) FFGAIN2 (P62)
These parameters define the second set of gains and accelerations. They must be set like the
parameters that define the first set.
To select the second set of gains and accelerations, set g.m.p. ACTGAIN2 (P108) correctly or
activate the CNC’s general logic input ACTGAIN2 (M5013).
DRIBUSLE (P63)
The CNC considers this parameter when using a digital drive (CAN). Axis parameter DRIBUSID
(P56) other than 0.
Even when the data exchange between the CNC and the drive is done via digital CAN bus, one must
define whether the feedback is also handled via bus or through the corresponding connector for the
axis or spindle.
POSINREF (P64)
Not being used.
Possible values
Integers between 0 and 64 times the value assigned to g.m.p. LOOPTIME (P72).
If LOOPTIME = 0 (4 ms), the maximum value that could be assigned to SMOTIME will
be 64 x 4 = 256 ms.
Default value: 0

Value Meaning
0 The feedback is done via connector.
1 The feedback is done via CAN.
First feedback (motor feedback).
DRIBUSLE = 0 The CNC controls the position loop.
The axis feedback is done via connector.
The command to the drive is sent out via CAN.
DRIBUSLE = 1 The CNC controls the position loop.
The axis feedback is done via CAN. First feedback (motor feedback).
The command to the drive is sent out via CAN.
