Digital Inputs
S1
MFDI selection 1
(ON: Forward run OFF: Stop)
• 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.
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: Install a jumper between terminals SC and 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: No jumper necessary between terminals SC-SN and terminals SC-SP.
S2
MFDI selection 2
(ON: Reverse run OFF: Stop)
S3
MFDI selection 3
(External fault (N.O.))
S4
MFDI selection 4
(Fault reset)
S5
MFDI selection 5
(Multi-step speed reference 1)
S6
MFDI selection 6
(Multi-step speed reference 2)
S7
MFDI selection 7
(Jog command)
S8
MFDI selection 8
(Baseblock command (N.O.))
SN MFDI power supply 0 V
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.
SC MFDI selection common
SP MFDI power 24 Vdc
Safe Disable
Input
H1 Safe Disable input 1
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.
H2 Safe Disable input 2
HC Safe Disable function common
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.

(Auxiliary frequency reference)
• Voltage input or current input
Select using DIP switch S1-3 and
H3-05 [Terminal A3 Signal Level Select] .
– -10 V to +10 V/-100% to +100% (input impedance: 20 kΩ)
– 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)
