(CN1-24) To use these signals, set " _ _ _ 1" in [Pr. PD34].
This signal is output when an alarm occurs.
When an alarm is not occurring, respective ordinary signals are output.
(CN1-23)
For details of the alarm codes, refer to chapter 8.
When "Enabled (absolute position detection system by DIO) (_ _ _ 1)" is
selected in [Pr. PA03] and when MBR, DB, or ALM is assigned to CN1-22
(CN1-22)
pin, CN1-23 pin, or CN1-24 pin, selecting alarm code output will generate
[AL. Parameter error].
CDPS turns on during gain switching.
ABSV turns on when the absolute position is undetermined.
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], CN1-22 pin will become ABSB0 only during ABS transfer mode.
(Refer to chapter 12.)
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], CN1-23 pin will become ABSB1 only during ABS transfer mode.
(Refer to chapter 12.)
(CN1-25) This is used to output ABS transmission data ready. When "Enabled
(absolute position detection system by DIO) (_ _ _ 1)" is selected in [Pr.
PA03], CN1-25 pin will become ABST only during ABS transfer mode.
(Refer to chapter 12.)
When a tough drive is enabled in [Pr. PA20], activating the instantaneous
power failure tough drive will turn on MTTR.
Connect
or 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).)
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].
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).)
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).)
CN1-10 This is used to enter a command pulse train.
CN1-35
For open-collector type (max. input frequency: 200 kpps)
Input the forward rotation pulse train between PP and DOCOM.
CN1-11
Input the reverse rotation pulse train between NP and DOCOM.
CN1-36
For differential receiver type (max. input frequency: 4 Mpps)
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].
