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]

• 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%
– 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.

Name (Default)
• Relay output
• 30 Vdc, 10 mA to 1 A
• 250 Vac, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)
• Relay output
• 30 Vdc, 10 mA to 1 A
• 250 Vac, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)

Note:
Do not set functions that frequently switch ON/OFF to MFDO (M1 to
M6) because this will decrease the performance life of the relay
contacts. Yaskawa estimates switching life at 200,000 times (assumes 1
A, resistive load).
