Moving Direction of the Linear Direct Drive System
When the motor is powered according to the circuit diagram, the push-rod is moving into the housing.
Thermal Motor Protection
| Sensor | Sensor Type |
|---|---|
| Temperature sensor 1 | PTC (6x, serial connected) |
| Temperature sensor 2 | Pt1000 temperature sensor (1x) |
| Description | Specification |
|---|---|
| PTC type | Nominal switch temperature TN: 100°C TN −5 K: RPTC < 550 Ω TN +5 K: RPTC > 1.33 kΩ |
| Pt1000 type | Temperature run linear: 3.851 Ω/K 0°C: RPt1000 ≈ 1000 Ω |
A safe electrical separation is not implemented in case of a direct connection of PTC or Pt1000 to the servo controller. The PTC is required to protect the motor against overtemperature. The Pt1000 temperature sensor provides temperature monitoring.

If using cable lengths of 5 m or more, stress peaks can appear at the motor clamps because of harmonic waves and reflections. These can exceed the DC link voltage and may damage the motor winding insulation. In this case, additional filters must be used. For details, refer to the operating manual.
