Parameter function：Simulation speed instruction zero fixed value setting is namely zero clamp.
When servo drive chooses speed mode and speed instruction given by external analog value, the analog voltage is 0, because of external
electromagnetic interference or zero drift and so on, can lead to motor can't rest. If need external analog input voltage near 0 V, the motor
must be stationary, then you can use this function.
When this function is adopted to meet the following two conditions：
 The absolute value of the speed instruction that input analog voltage corresponding is less than P1-44；
 The drive is defined as DI terminal of zero fixed signal ZCLAMP is effective.
When the above conditions are satisfied, servo drive switch from the speed mode to position mode automatically, make the motor in the
position to lock within ±1 pulse. Even under the action of external force, also returns zero clamp position.
NOTE：When use 2500ppr encoder, it‘s ±1pulse，When use 17bit encoder, it‘s ±3pulse.

Parameter function：Broadening of Z pulse. when PC can‘t capture a narrow Z pulse, then can broaden it.
Because the width of Z pulse will decrease with motor speed increase, for the convenience of matching with all kinds of PC, Z pulse width can
be adjusted according to actual situation. It set to 0 represents the output of Z pulse is original width of encoder Z signal.

Parameter function：Choosing the source of the motor output torque is limited.
P1-48=0：internal limit P1-46、P1-47 ；
P1-48=1： analog value1 limit，would be limited by P1-46、P1-47 at the same time；
P1-48=2： analog value2 limit，would be limited by P1-46、P1-47 at the same time；
P1-48=3：hold；
