 When the speed of the servomotor is lower than this parameter, digital output DO ZSP (zero
speed) is ON, otherwise is OFF.
 The comparator has hysteretic function set by parameter P161.

 When the following conditions satisfies, the zero speed clamp function will start:
Condition 1: In the speed control mode;
Condition 2: The ZCLAMP (zero speed clamp) is ON from DI input;
Condition 3: The speed command is lower than parameter P160.
 When any condition mentioned above does not satisfy, carries out the normal speed control.
 When zero speed clamp function started, the meanings of this parameter are:
0
： The position of the servomotor is fixed just when the clamp function starts. This time the
servo driver itself changes to the position control mode, and keeps the fixed point even
if an external force causes a displacement.
1 ： The speed command is forced to zero when the clamp function starts. The servo driver is
still in the speed control mode, but an external force can cause revolving.
