MTTR turns on when the instantaneous power failure tough drive operates
while the tough drive function selection is enabled with [Pr. PA20].
CLDS turns on during fully closed loop control.

pin No.
CN1-27 To use the signal in the speed control mode, enable TL (External torque
limit selection) with [Pr. PD23] to [Pr. PD28].
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).)
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
This is used to control torque in the full servo motor output torque range.
Apply 0 V to ±8 V DC between TC and LG. The maximum torque is
generated at ±8 V. (Refer to section 3.6.3 (1).) The speed at ±8 V can be
changed with [Pr. PC13].
If a value equal to or larger than the maximum torque is inputted to TC, the
value is clamped at the maximum torque.
CN1-2 Apply 0 V to ±10 V DC between VC and LG. Speed set in [Pr. PC12] is
provided at ±10 V. (Refer to section 3.6.2 (1).)
If a value equal to or larger than the permissible speed is inputted to VC,
the value is clamped at the permissible speed.
Resolution: 14 bits or equivalent
Apply 0 V to ±10 V DC between VLA and LG. Speed set in [Pr. PC12] is
provided at ±10 V. (Refer to section 3.6.3 (3).)
If a value equal to or larger than the permissible speed is inputted to VLA,
the value is clamped at the permissible speed.
CN1-10 This is used to enter a command pulse train.
CN1-35 For open-collector type
The maximum input frequency is 200 kpulses/s. For A-phase/B-phase
CN1-11
pulse train, 200 kpulses/s will be the frequency after multiplication by
CN1-36
four.
Input the forward rotation pulse train between PP and DOCOM.
Input the reverse rotation pulse train between NP and DOCOM.
For differential receiver type (max. input frequency: 4 Mpulses/s)
The maximum input frequency is 4 Mpulses/s. For A-phase/B-phase
pulse train, 4 Mpulses/s will be the frequency after multiplication by four.
Input the forward rotation pulse train between PG and PP.
Input the reverse rotation pulse train between NG and NP.
The command input pulse train form, pulse train logic, and command input
pulse train filter are changed in [Pr. PA13].
When the command pulse train is over 1 Mpulse/s and lower than 4
Mpulse/s, set [Pr. PA13] to "_ 0 _ _".
