Parameter Descriptions
6-02 Fire Mode Live Zero Timeout Function
Option: Function:
Select the timeout function when
fire mode is active. The function set
in this parameter is activated if the
input signal on analog inputs is
lower than 50% of the low value for
a time period defined in
parameter 6-00 Live Zero Timeout
Time.
[0] Off
*
[1] Freeze output Frozen at the present value.
[2] Stop Overruled to stop.
[3] Jogging Overruled to jog speed.
[4] Max. speed Overruled to maximum speed.
3.8.2 6-1* Analog Input 1
Parameters for configuring the scaling and limits for analog
input 1 (terminal 53).
6-10 Terminal 53 Low Voltage
Range: Function:
NOTICE
0.07 V [ 0 - par. 6-11
*
V]
For the live zero alarms to
work, parameter 6-10 Terminal
53 Low Voltage must have a
value of 1 V or greater.
Enter the low voltage value. This
analog input scaling value should
correspond to the low reference
feedback value set in
parameter 6-14 Terminal 53 Low Ref./
Feedb. Value.
6-11 Terminal 53 High Voltage
Range: Function:
10 V [ par. 6-10 - Enter the high voltage value. This
*
10 V] analog input scaling value should
correspond to the high reference
feedback value set in
parameter 6-15 Terminal 53 High
Ref./Feedb. Value.
6-12 Terminal 53 Low Current
Range: Function:
4 mA [ 0 - par. 6-13 Enter the low current value. This
*
mA] reference signal should correspond
to the low reference feedback value
set in parameter 6-14 Terminal 53
Low Ref./Feedb. Value. Set the value
M0010001

Function:
at >2 mA to activate the live zero
timeout function in
parameter 6-01 Live Zero Timeout
Function.
Function:
[ par. 6-12 - Enter the high current value
20 mA] corresponding to the high
reference/feedback set in
parameter 6-15 Terminal 53 High
Ref./Feedb. Value.
Function:
[-999999.999 Enter the analog input scaling value
- 999999.999 ] that corresponds to the low
voltage/low current set in
parameter 6-10 Terminal 53 Low
Voltage and parameter 6-12 Terminal
53 Low Current.
Function:
[-999999.999 Enter the analog input scaling value
- 999999.999 ] that corresponds to the high
voltage/high current value set in
parameter 6-11 Terminal 53 High
Voltage and parameter 6-13 Terminal
53 High Current.
Function:
NOTICE
[0.005 - 10 s]
This parameter cannot be
adjusted while the motor is
running.
Enter the filter time constant. This
constant is a first-order digital low-
pass filter time for suppressing
electrical noise in terminal 53. A
high value improves dampening
but also increases the delay
through the filter.
