(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.
(CN1-23)
For details of the alarm codes, refer to chapter 8.
When you select alarm code output while MBR or ALM is selected for
(CN1-49)
CN1-23, CN1-24, or CN1-49 pin, [AL. 37 Parameter error] will occur.
CDPS turns on during gain switching.
When a tough drive is enabled in [Pr. PA20], activating the instantaneous
power failure tough drive will turn on MTTR.
Connector
pin No.
CN1-27 To use the signal, enable TL (External torque limit selection) with [Pr.
PD03] to [Pr. PD20].
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 limited 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 The command input pulse train form, pulse train logic, and command input
pulse train filter are changed in [Pr. PA13].
CN1-37
For open-collector type, set [Pr. PA13] to "_ 3 _ _".
CN1-38
For differential receiver type, set [Pr. PA13] depending on the maximum
CN1-11
input frequency.
CN1-36
1) For open-collector type (sink input interface)
The maximum input frequency is 200 kpulses/s. For A-phase/B-phase
pulse train, 200 kpulses/s will be the frequency after multiplication by
four.
a) Sink input interface
Input the forward rotation pulse train between PP and DOCOM.
Input the reverse rotation pulse train between NP and DOCOM.
b) Source input interface
Input the forward rotation pulse train between PP2 and PG.
Input the reverse rotation pulse train between NP2 and NG.
2) For differential receiver type
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.
