12.3 - Explanation of parameters in
menu 10
: Drive healthy
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the drive is not in the trip state. If
parameter
10.36
is at 1, this bit will remain at 1 during the trip
phase if an auto-reset is supposed to occur. Once the number
of auto-resets is reached, the next trip will cause this bit to
change to zero.
: Drive active
Adjustment range : 0 or 1
0 (Disabled) (OFF)
1 (Enabled) (On)
This parameter is at 1 when the drive output is active.
: Zero speed
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the absolute value of the speed
is less than or equal to the threshold defined by parameter
3.05
.
10.03
changes back to 0 when the speed becomes greater
than
3.05
+ 10 rpm.
: Running at minimum speed
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
In bipolar mode (
1.10
= 1), the operation of this parameter is
identical to that of parameter
10.03
.
In unipolar mode (
1.10
= 0), this parameter is at 1 if the
absolute value of the ramp output is less than or equal to the
minimum speed
1.07
+ (30 rpm/number of pairs of motor
poles).
10.04
changes back to 0 when the speed becomes greater
than [
1.07
+ (30 rpm/number of pairs of poles) + 10 rpm].
The minimum speed is defined by parameter
1.07
.
: Below set speed
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the absolute value of the motor
speed is greater than
1.03
- (
3.06
÷ 2).
10.05
changes back to 0 when the speed becomes greater
than [
1.03
- (
3.06
÷ 2) + 10 rpm].
: At speed
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the absolute value of the motor
speed is between
1.03
- (
3.06
÷ 2) and
1.03
+ (
3.06
÷ 2).
: Above set speed
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the absolute value of the motor
speed is greater than
1.03
+ (
3.06
÷ 2).
10.07
changes back to 0 when the speed becomes less than
[
1.03
+ (
3.06
÷ 2) - 10 rpm].
: Nominal load reached
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when the active current
4.02
is at or
above the rated active current.
Rated active current =
5.07
x
5.10
.
: Drive output at current limit
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when drive current limiting is active.
: Drive regenerating
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when energy is being transferred from
the motor to the DC bus (driving load).
: Braking IGBT active
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when energy is being dissipated in the
optional braking resistor (provided it is connected).
: Braking resistor alarm
Adjustment range : 0 or 1
0 (Disabled) (OFF):
1 (Enabled) (On):
This parameter is at 1 when external resistance braking is
active and the cumulative braking power exceeds 75% of
10.39
.
Note: This alarm depends on the values set in
10.30
and
10.31
.
: Direction commanded
Adjustment range : 0 or 1
0 (Forward) (Fd): The pre-ramp reference is negative
(reverse).
1 (Reverse) (rSe): The pre-ramp reference is positive
(forward).
