2.5 Electrical connection

Before making any connections, make sure power to the electrical cabinet is off. This connection must
comply with the servoamplifier installation manual, and the cables selected from the range we offer (or
equivalent characteristics).
Choose cables with a cross-section large enough to prevent voltage drops.
If the cable is more than 25 m long, a filter may be required at the servoamplifier output: ask us for
details.
2.5.1 Thermal protection (as an option)
A thermal protector (PTC sensor) fitted in the servomotor winding trips the electronic system at 150° 
5° C.
The DIGIVEX supplies the sensor and processes the signal generated.
The PTC sensor, usually known as a thermistor, is a resistor made from semi-conductor material
whose resistance increases substantially with temperature.
This means a limit can be easily and reliably detected. The low thermal inertia of the sensor means
winding temperature variations can be monitored very closely and action taken as required.
2.5.2 Encoder option
2.5.3 Connecting
The connections are described in the appendix:
-
-
Rotation direction of the servomotor: In consideration with the recommended connection, a positive
speed input on the servoamplifier is followed by a rotation in the clockwise direction (seen from power
shaft side).
The connectors are adjustable (270°).
Caution: the precautionary measures for handling devices sensitive to
electrostatic discharges should be observed in the specific case of fitting a KTY
sensor.
Caution: the precautionary measures for handling device sensitive to
electrostatic discharges should be observed in the specific case of an encoder
option.
