4.1.3 Motor temperature protection TF, TH, KTY84, PT1000
Motors with internal temperature sensor (TF, TH, KTY84, PT1000 or similar) can be
directly connected to the inverter.
If the thermal protection is triggered, the inverter displays the error "F-PTC".
For motor protection monitoring, the following types can be selected:
• PTC-th for thermal sensor TF or bimetallic switch TH with trigger threshold 2.5 kΩ
• KTY84 in temperature classes B (120 °C), F(155 °C) and H (180 °C)
• PT1000 in temperature classes B (120 °C), F (155 °C) and H (180 °C)
Use a shielded cable for the motor sensor lead.
The motor temperature can be read out using index 11234.
INFORMATION
First configure the connected temperature sensor using parameter P2-33 before con-
necting the temperature sensor. Then connect the temperature sensor according to
the wiring diagram. Incorrect connection may lead to damage of sensor or inverter.

4.1.4 Connecting AC brakemotors
For detailed information about the SEW‑EURODRIVE brake system, refer to the "AC
Motors" catalog, which you can order from SEW‑EURODRIVE.
SEW‑EURODRIVE brake systems are disk brakes with a DC coil that release electri-
cally and brake using spring force. A brake rectifier supplies the brake with DC
voltage.
INFORMATION
The brake rectifier must have a separate supply system cable for inverter operation.
Supply via the motor voltage is not permitted.
