Table 3.13 Drive Multi-function Input Terminals
Name (Default)
Multi-Function Digital Input
• Photocoupler
• 24 V, 6 mA
Note:
Install the wire jumpers between terminals SC-SP and SC-SN to set the MFDI power supply
(sinking/sourcing mode or internal/external power supply).
• Sinking Mode: Install a jumper between terminals SC and SP.
• Sourcing Mode: Install a jumper between terminals SC and SN.
• External power supply: No jumper necessary between terminals SC-SN and terminals SC-SP.
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.
Safe Disable Input
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 2 ms.
Note:
Safe disable inputs are only effective in Drive Mode. They will not function in Bypass Mode.
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.
Power Supply for Multi-Function Analog Input
• 10.5 V (allowable current 20 mA maximum)
Voltage input or current input
Select terminal A1 with Jumper switch S1 and H3-01 [Terminal A1 Signal Level Select].
• 0 V to 10 V/100% (input impedance: 20 kΩ)
• 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance: 250 Ω)
Voltage input or current input
Select terminal A2 with Jumper switch S1 and H3-09 [Terminal A2 Signal Level Select]
• 0 V to 10 V/100% (input impedance: 20 kΩ)
• 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance: 250 Ω)
Signal Ground for Multi-Function Analog Input
• 0 V

Function (Signal Level)
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.
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
