ABB ACQ80-04 - Frequency Reference Chain

Parameters 101
25.53 Torque prop
reference
Shows output of the proportional (P) part of the speed
controller.
This parameter is read-only.
0.0
-30000.0…
30000.0%
P-part output of speed controller. See par.
46.03
25.54 Torque integral
reference
Shows output of the integral (I) part of the speed controller.
This parameter is read-only.
0.0
-30000.0…
30000.0%
I-part output of speed controller. See par.
46.03
25.55 Torque deriv
reference
Shows output of the derivative (D) part of the speed
controller.
This parameter is read-only.
0.0
-30000.0…
30000.0%
D-part output of speed controller. See par.
46.03

28 Frequency reference
chain
Settings for the frequency reference chain.
28.01 Frequency ref ramp
input
Shows used frequency reference before ramping.
This parameter is read-only.
0.00
-500.00…500.00
Hz
Frequency reference before ramping. 10 = 1
28.02 Frequency ref ramp
output
Shows final frequency reference (after selection, limitation
and ramping).
This parameter is read-only.
0.00
-500.00…500.00
Hz
Final frequency reference. 10 = 1
28.72 Freq acceleration
time 1
Defines acceleration time 1 as the time required for the
frequency to change from zero to the frequency defined by
parameter 46.02 Frequency scaling. After this frequency has
been reached, the acceleration continues with the same rate
to the value defined by parameter 30.14 Maximum frequency.
If the reference increases faster than the set acceleration
rate, the motor will follow the acceleration rate.
If the reference increases slower than the set acceleration
rate, the motor frequency 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.
Note: Applicable only when 79.40 MPPT reference is
disabled. If parameter MPPT reference is enabled, then the
parameter should be set to it’s default value
20.000 s
0.000…1800.000 s Acceleration time 1. 10 = 1 s
