completed
MSDL
After MSD (Mark detection) is turned on, turning off MSD will turn on
MSDL.
DO-1
Alarm code
ACD0 (CN1-24) To use these signals, set " _ _ _ 1" in [Pr. PD34].
This signal is outputted when an alarm occurs.
When an alarm is not occurring, respective ordinary signals are outputted.
For details of the alarm codes, refer to chapter 8.
DO-1
ACD1 (CN1-23)
ACD2 (CN1-22)
Variable gain
selection
CDPS
CDPS turns on during gain switching.
DO-1
Absolute position
undetermined
ABSV
ABSV turns on when the absolute position is undetermined.
DO-1
During tough
drive
MTTR
When a tough drive is "Enabled" in [Pr. PA20], activating the instantaneous
power failure tough drive will turn on MTTR.
DO-1
During fully
closed loop
control
CLDS
CLDS turns on during fully closed loop control.

CP CL PS
Manual pulse
generator
PP
(CN1-10) Connect the manual pulse generator (MR-HDP01).
When using the signal, enable PP and NP with [Pr. PD44] and [Pr. PD46].
DI-2
NP (CN1-35)
Analog torque
limit
TLA
CN1-27 When using the signal, enable TL (External torque limit selection) with [Pr.
PD04], [Pr. PD06], [Pr. PD08], [Pr. PD10], [Pr. PD12], [Pr. PD14], [Pr.
PD18], [Pr. PD20], [Pr. PD22], [Pr. PD44], and [Pr. PD46].
When TLA is enabled, torque is limited in the full servo motor output torque
range. Apply 0 V to +10 V DC between TLA and LG. Connect the positive
terminal of the power supply to TLA. The maximum torque is generated at
+10 V. (Refer to section 3.6.1 (5) of "MR-J4-_A_(-RJ) Servo Amplifier
Instruction Manual".)
If a value equal to or larger than the maximum torque is inputted to TLA,
the value is clamped at the maximum torque.
Resolution: 10 bits
Analog
input
Analog override
VC
CN1-2
The signal controls the servo motor setting speed by applying -10 V to
+10V to between VC and LG. The percentage will be 0% with -10 V, 100%
with 0 V, and 200% with +10 V to the setting speed of the servo motor.
Resolution: 14 bits or equivalent
Analog
input
