Note
● [Note 1] If the ambient temperature exceeds 23℃, the output current must be
derated by 1.8 mA for every additional 1℃. The maximum output current is 170
mA at 40℃. When OP and 24V are shorted, the maximum output current is
calculated by the following formula: 170 mA minus current over the DI.
● [Note 2] Based on the maximum output voltage of the signal source, select 500 Ω
or 250 Ω impedance. For example, if 500 Ω is selected, the maximum output
voltage cannot be lower than 10 V so that AI2 can measure 20 mA current.
5.8.4 Inspection After Wiring
After wiring is completed, inspect the items in the following table and tick compliant
items.
Table 5–17 Post‑wiring inspection checklist
No. Item
Compliance
1
The power supply input cables are connected
to the R, S, and T terminals.
2
The motor input cables are connected to the
U, V, and W terminals.
3
The dimensions of the main circuit cables
meet the requirements.
4
Heat‑shrink tubes are applied to cable lug
copper pipes and conductors of main circuit
cables, and completely cover the cable
conductors.
5
The motor output cable does not exceed 50 m.
Otherwise, the carrier frequency needs to be
reduced according to the setting of F0‑15.
6
The ground cables are connected correctly.
7
The output terminals and control signal
terminals are securely fastened.
8
The braking resistor and braking unit (if used)
are connected correctly and have proper
resistance.
9
The control circuit cables are shielded twisted
pairs.
10
Optional cards are connected correctly.
