for a list of Output terminals and functions.
• Photocoupler
• 24 V, 6 mA
Note:
To set the MFDI power supply (Sinking/Sourcing Mode or internal/
external power supply), install or remove a jumper between
terminals SC-SP or SC-SN depending on the application.
• Sinking Mode, Internal power supply: Install the jumper to close
the circuit between terminals SC-SP.
NOTICE: Damage to Equipment. Do not close
the circuit between terminals SC-SN. If you
close the circuits between terminals SC-SP and
terminals SC-SN at the same time, it will cause
damage to the drive.
• Sourcing Mode, Internal power supply: Install the jumper to close
the circuit between terminals SC-SN.
NOTICE: Damage to Equipment. Do not close
the circuit between terminals SC-SP. If you
close the circuits between terminals SC-SP and
terminals SC-SN at the same time, it will cause
damage to the drive.
• External power supply: Remove the jumper from the MFDI
terminals. It is not necessary to close the circuit between terminals
SC-SP and terminals SC-SN.
MFDI power supply, 24 V (maximum 150 mA)
NOTICE: Damage to Equipment. Do not close the
circuit between terminals SP-SN. If you close the
circuits between terminals SC-SP and terminals
SC-SN at the same time, it will cause damage to
the drive.
Remove the jumper between terminals H1-HC and H2-HC to use the
Safe Disable input.
• 24 V, 6 mA
• ON: Normal operation
• OFF: Coasting motor
• Internal impedance 4.7 kΩ
• OFF Minimum OFF time of 3 ms.
Safe Disable function common
NOTICE: Do not close the circuit between
terminals HC and SN. A closed circuit between
these terminals will cause damage to the drive.
• Response frequency: 0 to 32 kHz
• H level duty: 30% to 70%
• H level voltage: 3.5 V to 13.2 V
• L level voltage: 0.0 V to 0.8 V
• Input impedance: 3 kΩ
10.5 V (allowable current 20 mA maximum)
Voltage input
Use H3-01 [Terminal A1 Signal Level Select] to select the signal level.
• 0 V to 10 V/ 100% (input impedance: minimum 15 kΩ)
• -10 V to +10 V/-100% to +100% (input impedance: minimum 15
kΩ)
Voltage input or current input
Use DIP switch S1 and H3-09 [Terminal A2 Signal Level Select] to
select the input.
• 0 V to 10 V/ 100% (input impedance: minimum 15 kΩ)
• -10 V to +10 V/-100% to +100% (input impedance: minimum 15
kΩ)
• 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance: 250
Ω)
