These are the bits to select the function of the motor excitation, sequence
current limit, or dynamic brake when an emergency stop or a servo OFF is
input, or the main power supply is turned OFF.
(Note) When the Bit4 and Bit3 are to be set to " 00" and " 01" respectively

External type
To use the external- type regeneration resistor, set
this bit to " 1."
Bit1

Detect
When the motor load inertia is large, a speed error may
be
detected
undershooting at the time of the startup or the stop. In
that case, set this bit t o " 0."
Bit2
Retention brake timing output
0
With 300- msec delay
1
Without delay
In order to prevent falling by self- weight when the
servo amplifier is switched from OFF to ON, or from ON
to OFF on the vertical axis, use the retention brake
timing output of the servo amplifier, and set this bit to
" 0."
Handling in case of Emergency Stop/ servo Off
Bit3
input/ main power supply OFF
0
Stop is made by the sequence current limit, then
the motor excitation is turned off.
1
Motor stop is made by the peak torque, the
motor excitation is turned off.
0
In the case of an Emergency Stop, stop is made
by the dynamic brake. In the case of servo
OFF/ main power supply OFF, stop is made by
the sequence current limit.
1
Setting prohibited
(after the motor stops, the motor excitation is turned off), set the
retention brake timing output of Bit2 to " 0."
