Description
Displays the value of the speed reference (Ext1 or Ext2) that
has been selected by 19.11 Ext1/Ext2
at 22.11 Ext1 speed ref1
406.
This parameter is read-only.
Speed reference after additive 2.
Displays the value of speed reference before application of
critical speeds. See the control chain diagram on page 407.
The value is received from
unless overridden by
• any constant speed
• network control reference
• control panel reference
• safe speed reference.
This parameter is read-only.
Speed reference before application of critical speeds.
Speed reference ramp settings (programming of the
acceleration and deceleration rates for the drive).
See the control chain diagram on page 408.
Displays the used speed reference (in rpm) before it enters
the ramping and shaping functions. See the control chain
diagram on page 408.
This parameter is read-only.
Speed reference before ramping and shaping.
Displays the ramped and shaped speed reference in rpm.
See the control chain diagram on page 408.
This parameter is read-only.
Speed reference after ramping and shaping.
Defines acceleration time 1 as the time required for the speed
to change from zero to the speed defined by parameter
Speed scaling (not to parameter
If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the acceleration
rate.
If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.
