5 Operation
5.3.5 Zero Clamp Function
(1) Factory-set Sequence Signal Allocations (Pn50A.0 = 0)
When Pn000.1 is set to A, the control method becomes "speed control <=> speed control with zero clamp
function" and the /P-CON signal is used as a zero clamp signal.
Input
Pn000
(2) Changing Sequence Signal Allocations for Each Signal (Pn50A.0 = 1)
Use the /ZCLAMP signal when switching to zero clamp operation.
To use the /ZCLAMP signal, the input signal must be allocated. For details, refer to 3.3.1 Input Signal Alloca-
tions.
Input
To use the zero clamp function, set Pn000.1 to 0, 3, 4, 5, 6, 7, 9 or A.

function
Setting
If the input voltage of the speed reference (V-REF) drops
ON below the set speed in the zero clamp level (Pn501), the zero
clamp function will turn ON.
OFF Turns OFF the zero clamp function.
Control Method
Setting
The zero clamp function will be turned ON if the input volt-
ON age of the speed reference (V-REF) drops below the set speed
in the zero clamp level. (Pn501)
OFF Turns OFF the zero clamp function.
