FAULTS AND ALARMS
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.
Table 10.1: Levels of performance monitoring of the DC link voltage
Supply Level F021 Level F022
110 to 127 Vca (P296 = 1) 200 Vcc 460 Vcc
200 to 240 Vca (P296 = 2) 200 Vcc 410 Vcc
380 Vac (P296 = 4) 385 Vcc 800 Vcc
400 to 415 Vca (P296 = 5) 405 Vcc 800 Vcc
440 to 460 Vca (P296 = 6) 446 Vcc 800 Vcc
480 Vca (P296 = 7) 486 Vcc 800 Vcc
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 11-1. The temperature controlled by a fan according to parameter
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 Table 10.2 on page 10-4:
