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.

[Min Speed Fwd]

motor. Speed reference values below the value in this parameter are
clamped until the reference exceeds this limit.

[Preset Speed 6]
[Preset Speed 7]
Provides an internal fixed speed command value. In bipolar mode,
direction is commanded by the sign of the reference.
Note: [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.
