Use shielded cable on each pair. The thermal
sensor is connected in the motor terminal box (1)
(1) The thermal sensor connected in the motor terminal box should be connected to terminals 8 and 11 of the drive control terminal
block. To modify sensor control, see parameter
7.15
(
0.21
).
(2) Connect the shielding 360° round the connector.
(3) Connect the shielding 360° round the shielding connection holder.
