Wiring of cooling fan motor and motor with thermal protector
17
<Precautions>
1. The thermal protector (TP) is an automatic reset type. To prevent hazards caused by restarting, connect the
TP as shown above. Don't connect TP directly to the power supply.
2. Once the TP operates, cooling period is required before the operation can restart.
3. Connect the cooling fan motor (F) across pins 1 and 2 on the power terminal.
4. Motor (M) and tachometer generator (TG) should be connected according to corresponding wiring diagram
shown later.
Wiring to electromagnetic brake
18
• Variable speed motor with electromagnetic brake should be wired as shown below.
<Precautions>
1. SW9 should be switched to RUN or STOP at the same time as the other switches are switched to RUN or
STOP.
If the other switches are set to RUN while the brake is energized (SW9 in STOP position), the motor will
generate heat.
2. For other wirings, refer to the corresponding circuit/wiring diagrams.
If the application is speed change without using electric braking (page C-14), perform wiring according to
“Start/stop control with small signal”.

• Features
• First DIN 48 size in the industry
Compact space saving model (control panel)
(standardized panel machining holes)
A wide choice of options (recommended by Matsushita
Electric Works, Ltd.)
• Simplified and neat wiring arrangement
Main circuit and signal inputs are isolated on the terminal
block.
Use of 8-pin terminal block requires fewer wiring
connections.
• Can operate under a wide range of power supply voltage
(100V 100 to 120V, 200V 200 to 240V)
• Standard specification

3. Electric braking has no mechanical brake holding force.
To provide the holding force, use a variable speed motor with electromagnetic braking feature.
