Pn005
H.□□A□
Control mode: Speed control(analog voltage reference) Zero Clamp
Zero Clamp Conditions:
Zero clamp is performed with Pn005=H.□□A□ when the following two conditions are both satisfied:
·/P-CON is ON (low level)
·Speed reference (V-REF) drops below the setting in Pn502.

Sets the servomotor speed at which the zero clamp is performed if zero clamp speed control(Pn005=H.□□A□) is
selected. Even if this value is set higher than the maximum speed of the servomotor, the maximum speed will be used.

/P-CON and /ZCLAMP are the input signals to switch to the zero clamp function.
■Important
In speed control (analog voltage reference) mode,when /ZCLAMP is allocated to an output terminal,zero clamp
function is enabled.
