Limits
1
[Minimum Speed]
Defines the minimum speed of the drive. This value applies to both directions
of motor rotation for four quadrant drives. A speed below the value set in
[Minimum Speed] is not possible, regardless of the set speed reference value.
If the value of [Minimum Speed] is changed, Pars 5 [Min Speed Fwd] and 6
[Min Speed Rev] are set to the same value. If either Par 5 [Min Speed Fwd] or
Par 6 [Min Speed Rev] is changed later, the last change is valid.

[Maximum Speed]
Defines the maximum speed of the drive. This value applies to both
directions of motor rotation for four quadrant drives. The value of this
parameter is input to the speed regulator and therefore takes into account
the reference value that comes from the ramp as well as the direction of
rotation. If the value of [Maximum Speed] is changed, Pars 3 [Max Speed
Fwd] and 4 [Max Speed Rev] are set to the same value. If either Par 3 [Max
Speed Fwd] or Par 4 [Max Speed Rev] is changed later, the last change is
valid.

[Max Speed Fwd]
Defines the maximum speed for forward (clockwise) rotation of the motor.
The value of [Max Speed Fwd] affects the input of the speed regulator and
therefore takes into account both the reference values that come from the
ramp as well as the direction of motor rotation.

[Max Speed Rev]
Defines the maximum speed for reverse (counterclockwise) rotation of the
motor for four quadrant drives only. The value of [Max Speed Rev] affects the
input of the speed regulator and therefore takes into account both the
reference values that come from the ramp as well as the direction of rotation.

the reference exceeds this limit.

[Preset Speed 7]
Provides an internal fixed speed command value. In bipolar mode, direction
is commanded by the sign of the reference.
Notes: [Preset Speed 1] cannot be directly selected by the Speed Sel digital
inputs. However, Par 154 [Preset Speed 1] can be directed to Par 42 [Trim
Ramp] via the Scale Block parameters. See Reference Control on page
for
more information.
