• DC30 V, 10 mA to 1 A
• AC250 V, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)

(Brake Release Command)
• Relay output
• DC30 V, 10 mA to 1 A
• AC250 V, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)
Note:
Switching life is estimated at 8,000,000 times (assumes 30 mA, inductive load) or 200,000
times (assumes 1 A, resistive load). When switching inductive load such as relay coils,
connect surge absorbing element in parallel against the load for effective protection of relay
contact.

• Photocoupler output
• 48 V, 2 mA to 50 mA
Note:
Connect a flywheel diode as shown in Figure 2.106 when driving a reactive load such as a
relay coil. Ensure the diode rating is greater than the circuit voltage.

Type Terminal Name (Default) Function
External Power Supply Input
Terminals
PS External 24 V power supply input
Supplies backup power to the drive control circuit, keypad, and option board.
21.6 VDC to 26.4 VDC, 700 mA
AC External 24 V power supply ground 0 V
Alarm Display When You Use External 24 V Power Supply
When you use an external 24 V power supply, the drive detects an alarm as shown in Table 2.19 if you set o2-23
[External 24V Powerloss Detection]
and
o2-26 [Alarm Display at Ext. 24V Power]
for the main circuit power
supply. Set the alarm display as necessary.
