Vertical axis

n amount
Set the compensation amount of the vertical axis freefall prevention function.
Set it per servo motor rotation amount.
When setting a positive value, the servo motor moves in the direction set with [Pr.
PA14] for the forward rotation pulse input. When setting a negative value, the servo
motor moves in the direction set with [Pr. PA14] for the reverse rotation pulse input.
For example, if a positive compensation amount is set when the [Pr. PA14 Rotation
direction selection/travel direction selection] setting is "1", compensation will be
performed to the CW direction.
The vertical axis freefall prevention function is performed when all of the following
conditions are met.
1) Position control mode
2) The value of the parameter is other than "0".
3) The forced stop deceleration function is enabled.
4) Alarm occurs or EM2 turns off when the servo motor speed is zero speed or
less.
5) MBR (Electromagnetic brake interlock) is enabled with [Pr. PD23] to [Pr. PD26],
[Pr. PD28], and [Pr. PD47], and the base circuit shut-off delay time is set in [Pr.
PC16].

warning level
Set an error excessive warning level.
To enable the parameter, select "Enabled (1 _ _ _)" of "[AL. 9B Error excessive
warning] selection" in [Pr. PC60].
You can change the setting unit with "Error excessive alarm/error excessive warning
level unit selection" in [Pr. PC24].
Set this per rev. Setting "0" will be "1 rev", and setting over 200 rev will be clamped
with 200 rev.
When an error reaches the set value, [AL. 9B Error excessive warning] will occur.
When the error decreases lower than the set value, the warning will be canceled
automatically. The minimum pulse width of the warning signal is 100 [ms].
Set as follows.: [Pr. PC73 Error excessive warning level] < [Pr. PC43 Error
excessive alarm level] When you set as follows, [AL. 52 Error excessive] will occur
earlier than the warning.: [Pr. PC73 Error excessive warning level] ≥ [Pr. PC43 Error
excessive alarm level]
