P358 - Encoder Fault Config.
Range: 0 = Inactive
1 = F067 ON
2 = F079 ON
3 = F067 and F079 ON
Properties: cfg
Description:
This parameter allows individually disabling the fault detection by software: a) F067 - Inverted Encoder/Motor Wiring
and b) F079 - Encoder Signal Fault. The verification by software of faults F067 and F079 will remain disabled when
P358 = 0.

10.3 PROTECTIONS

This section contains information on the internal protections of the inverters and the motors. Refer to the user's
manual and the product quick reference for further information.

10.3.1 Inverter

The inverter has several levels of internal protection. Among them, we can point out:

10.3.1.1 DC Link Voltage Supervision

The DC link voltage is constantly compared to the maximum and minimum values according to the inverter power
supply, as shown in Table 10.1 on page

10.3.1.2 Temperature control

The temperature of the power module is read via internal temperature sensor and displayed in parameter P030
(more information on Chapter 11 READ on page
P352.
P352 - Fan Control Config.
Range: 0 = OFF
1 = ON
2 = CT
Properties: cfg
Description:
The inverter is equipped with a heatsink fan, and the activation will be controlled via software by means of the
inverter programming.
The options available to set this parameter are described in
10-3.
