Output Terminals
Refer to Table 5.8 and Table 5.9
386
Table 5.7 Multi-function Input Terminals
Name (Default)
• 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.
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 SN. A
closed circuit between these terminals will cause damage to the drive.
• Response frequency: 0 Hz 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)
-10.5 V (allowable current 20 mA maximum)
Voltage input or current input
Select terminal A1 with DIP switch S1-1 and H3-01 [Terminal A1 Signal Level Select].
Select terminal A2 with DIP switch S1-2 and H3-09 [Terminal A2 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 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)
• PTC input (Motor Overheat Protection)
Set DIP switch S4 to "PTC" and set DIP switch S1-3 to "V" to set terminal A3 for PTC input.

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.
