H Parameters Requiring Setting
Parameter No. Parameter name Explanation Reference
Pn50A.3
Pn50b.0
Input signal selection 1:
POT signal selection
Input signal selection 2:
NOT signal selection
You must allocate both POT
and NOT. (See note.)
4-4-3 Important Parameters
Pn001 Function selection switch 1 Set the stop method when
POT and NOT in Pn001.1
(stop selection for drive
prohibition input) are OFF.
If Pn001.1 is set to 0 (stop
according to Pn001.0
setting), be sure to set Pn
001.0 (stop selection for
alarm generation with servo
OFF).
4-4-3 Important Parameters
Pn406 Emergency stop torque If Pn001.1 is set to 1 or 2,
set emergency stop torque
in Pn406.
4-4-4 Parameter Details
Note POT and NOT are allocated to CN1-42, 43 in the default settings, but are both set to disabled (i.e.,
drive prohibition will not operate). If changing the default setting, set Pn50A.0 (input signal selec-
tion mode) to 1 (user-defined settings).

Note 1. If the Servomotor stops in this mode during position control, the position loop is disabled.
Note 2. The position method used during torque control depends on Pn001.0 setting (the P001.1 set-
ting is unrelated).
Note 3. With a vertical load, the load may fall due to its own weight if it is left at a drive prohibit input. We
recommend that you set the stop method for the drive prohibit input (Pn001.1) for decelerat-
ing with the emergency stop torque, and then set stopping with the servo locked (SV: 1) to
prevent the load from falling.
