Note: This value must be less than or equal to the value of
25.03 Crit speed1 hi.
Low limit for critical speed 1.
Defines the high limit for critical speed range 1.
Note: This value must be greater than or equal to the value of
25.02 Crit speed1 lo.
High limit for critical speed 1.
Defines the low limit for critical speed range 2.
Note: This value must be less than or equal to the value of
25.05 Crit speed2 hi.
Low limit for critical speed 2.
Defines the high limit for critical speed range 2.
Note: This value must be greater than or equal to the value of
25.04 Crit speed2 lo.
High limit for critical speed 2.
Defines the low limit for critical speed range 3.
Note: This value must be less than or equal to the value of
25.07 Crit speed3 hi.
Low limit for critical speed 3.
Defines the high limit for critical speed range 3.
Note: This value must be greater than or equal to the value of
25.06 Crit speed3 lo.
High limit for critical speed 3.
Constant speed selection and values. An active constant
speed overrides the drive speed reference. See section
Constant speeds on page 31.
Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed.
Information
1 = Packed: 7 constant speeds are selectable using the three sources
defined by parameters 26.02,
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters 26.02,
In case of conflict, the constant speed with the smaller number takes
priority.
1 = Start dir: To determine running direction for a constant speed, the
sign of the constant speed setting (parameters 26.06...26.12) is
multiplied by the direction signal (forward: +1, reverse: -1). For example,
if the direction signal is reverse and the active constant speed is
negative, the drive will run in the forward direction.
0 = Accord Par: The running direction for the constant speed is
determined by the sign of the constant speed setting (parameters
26.06...26.12).
Parameters 137
26.03 and 26.04.
