Table 4-4 Parameter Adjustments - Continued
Parameter Factory Setting Description
CUTBACK SPEED 100% Typically from 10% to 100%. It determines the percentage of the
max speed applied when the cutback switch 1 (SR#1 on CNA#15
(
Table 4-5 ) is active. When set to 100% the speed reduction is
ineffective.
CUTBACK SPEED 2 37% Typically from 10% to 100%. It determines the percentage of the
max speed applied when the cutback switch 2 (SR#2 on CNA#14
(
Table 4-5 ) is active. When set to 100% the speed reduction is
ineffective.
HS CUTBACK 100% Typically from 10% to 100%. It determine the percentage of the
max speed applied when the Hard & Soft function (H&S switch on
CNB#4 (
Table 4-5 ) is active. When set to 100% the speed reduc-
tion is ineffective.
FREQUENCY
CREEP
5.00 Hz Hz value. This is the minimum speed applied when the forward or
reverse switch is closed, but the accelerator at its minimum. In the
ACO sense Coils this setting is higher equal than 5 Hz.
RPM CREEP 100% A Percentage value. Set to 100% and not Used.
MAXIMUM
CURRENT
96% It specifies the percentage of the absolute current (150A) at which
the current will be limited. Normally MAXIMUM CURRENT is
100%. DO NOT CHANGE.
INCHING SPEED 0 Hz Hz value. It determines the speed when the “Inching function” is
active.
INCHING TIME LEVEL = 0 Level 0 to 9. It determines the duration time when the “Inching func-
tion” is active.
AUXILIARY TIME 1 Time units value (seconds). For the encoder version, it determines
the time duration (in seconds) in which the
the frequency was arrived to zero.
ANTIROLLBACK 80% A Percentage of the Maximum Current. This setting increases the
phase current when low frequency during starting operation. It is
used to push up, in feedforward way, the torque when it is not
possible to control the flux, in feedback way, because of the low
frequency.
