“Factor brake current” parameter
The “factor brake current” parameter defines the factor by
which the traversing current is increased during braking ope-
rations.
1 ... 2.5 (default: 1)
The braking current is i
brake
= 1 ... 2.5 × i
drive
.
The brake current must not exceed 2.28 A.
“Factor boost current” parameter
The “factor boost current” parameter defines the factor by
which the traversing current is increased during accelerating
operations.
1 ... 2.5 (default: 1)
The accelerating current is i
acc
= 1 ... 2.5 × i
drive
.
The accelerating current must not exceed 2.28 A.
“Max. overcurrent duration” parameter
The “max. overcurrent duration” parameter defines how long
the traversing current is increased for during braking and ac-
celerating operations.
0 ... 2,500 (default: 0)
The traversing current is increased for a maximum of
0 ... 2,500 ms during braking and accelerating operations.
“Axis mode” parameter
The “axis mode” parameter defines the specification of the
traversing range.
linear (default)
The traversing range is limited on both sides. Absolute positi-
oning is only possible within the traversing range. The traver-
sing range can be exited through relative positioning.
modulo
The traversing range is repeated. On passing the traversing
range limit, the internal position counting is continued from
the other traversing range limit.
“Diagnostic alarm” parameter
The “diagnostic alarm” parameter activates diagnostic
alarms.
Disabled (default)
Diagnostic alarms are deactivated.
Enabled
Diagnostic alarms are activated.
“Function DI” parameter
The “function DI” parameter defines the function of the asso
-
ciated digital input.
Digital input
The input works as a general digital input.
Encoder sig. A
The input records the signal of a rotary encoder (channel A).
Encoder sig. B
The input records the signal of a rotary encoder (channel B).
Limit switch left/ccw
The input records the signal of a limit switch. The limit
switch is started up by the stepper motor in a counter-clock-
wise direction.
Limit switch right/cw
The input records the signal of a limit switch. The limit switch
is started up by the stepper motor in a clockwise direction.
Jog left/ccw
The input records the signal for triggering jog mode in a
counter-clockwise direction.
Jog right/ccw
The input records the signal for triggering jog mode in a
clockwise direction.
Zero track
The input records the zero track signal of a rotary encoder.
Ref. switch left/ccw
The input records the signal of a reference switch. The refe-
rence point is started up by the stepper motor in a counter-
clockwise direction.
Ref switch right/cw
The input records the signal of a reference switch. The refe-
rence point is started up by the stepper motor in a clockwise
direction.
