• 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).
32 kHz (maximum)
Refer to "Pulse Train Output" on page
Select voltage or current output.
• 0 V to 10 V/0% to 100%
• -10 V to +10 V/-100% to +100%
• 4 mA to 20 mA (receiver recommended impedance: 250 Ω)
Note:
Select with jumper switch S5 and H4-07 [Terminal FM Signal Level Select] or H4-08
[Terminal AM Signal Level Select].
0 V
Supplies backup power to the drive control circuit, keypad, and option board.
