4.2.31 Zero current detection (Pr. 152, Pr. 153)
Pr. 152 "zero current detection level"
Pr. 153 "zero current detection time"
When the inverter's output current falls to "0", torque will not be generated. This may
cause a gravity drop when the inverter is used in vertical lift application.
To prevent this, the output current "zero" signal can be output from the inverter to close
the mechanical brake when the output current has fallen to "zero".
"
If the output current remains lower than the Pr. 152 setting during inverter operation
for longer than the time set in Pr. 153, the zero current detection (Y13) signal is
output.
(Use any of Pr. 190 to Pr. 192 to assign the terminal (remote input) used for Y13
signal output.)

Refer to the following list and set the parameters:
Parameter
Number
Description
152
Set the zero current detection level.
Set this parameter to define the percentage of the rated current at which the
zero current will be detected.
153
Set the zero current detection time.
Set a period of time from when the output current falls to or below the
Pr. 152 setting to when the zero current detection signal (Y13) is output.
Note: 1. If the current rises above the preset detection level and the condition is not
satisfied, the zero current detection signal is held on for about 100ms.
2. This function is also valid during execution of offline auto tuning.
3. When the terminal (remote input) functions are changed using Pr. 190 to
Pr.192, the other functions may be affected. Confirm the functions of the
corresponding terminals (remote input) before making setting.
