This parameter can be assigned to a programmable analog output.
Speed ref
Total speed reference value in rpm
Speed reg output
Output value of the speed regulator, used as the reference value for the current regulator
n
ote
!
The speed regulator is still active even if disabled (
Enable spd reg
= Disabled),
therefore the
Speed reg output
contains valid information also in this case. Such
a data can be transferred to the APC300 board to be used for other regulation.
If the speed regulator is enabled (
Enable spd reg
= Enabled) the
Speed reg
output
contains the sum of the actual speed regulator output and
T current
ref 2
.
Lock speed reg
This parameter is used in order to lock the speed regulator. When this happens, it stops
to work, the current reference value is set to zero and the drive comes to a stop. This
coasting time then depends on the rotating mass and the friction within the system
concerned. If the connection between the speed regulator and the current regulator is
restored, the drive will restart in the shortest possible time.
ON
Speed regulator locked (= 0 V when using a digital input).
OFF Speed regulator unlocked (= 15...30 V when using a digital input).
Enable spd reg
This enables dynamic switching, with the drive enabled or disabled, from speed control
to torque control by changing the parameter selection:
Enabled
The speed regulator is enabled. The speed regulator output
becomes the current regulator input.
Speed reg output
=
T
current ref 1
.
Disabled
The speed regulator is blocked, parameter
T current ref 1
(IPA
39) becomes the current regulator reference.
Lock speed I
Not active (H)
I component of the speed regulator is enabled
Active (L)
I component of the speed regulator is disabled
