Table 3.4 Digital Inputs
• Photocoupler
• 24 V, 6 mA
Note:
Install the wire jumpers between terminals DIC-D24V and DIC-D0V to set the MFDI power supply (sinking/
sourcing mode or internal/external power supply).
• Sinking Mode: Install a jumper between terminals DIC and D24V.
NOTICE: Do not close the circuit between terminals DIC and D0V in Sinking
Mode. Failure to obey will cause damage to the drive.
• Sourcing Mode: Install a jumper between terminals DIC and D0V.
NOTICE: Do not close the circuit between terminals DIC and D24V in Source
Mode. Failure to obey will cause damage to the drive.
• External power supply: No jumper necessary between terminals DIC-D0V and terminals DIC-D24V.
MFDI power supply, 24 V (maximum 150 mA)
NOTICE: Do not close the circuit between terminals D24V and D0V. Failure to
obey will cause damage to the drive.
Table 3.5 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.
Safe Disable function common
NOTICE: Do not close the circuit between terminals HC and D0V. Failure to obey
will cause damage to the drive.
Table 3.6 Master Frequency Reference

Voltage input or current input
Select terminal AI1 with DIP switch S1-1 and H3-01 [AI1 Signal Level Select].
Select terminal AI2 with DIP switch S1-2 and H3-09 [AI2 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)
• Voltage input or current input
Select with DIP switch S1-3 and H3-05 [AI3 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)
• PTC input (Motor Overheat Protection)
Set DIP switch S4 to "PTC" and set DIP switch S1-3 to "V" to set terminal AI3 for PTC input.
