The value of P0013 is indicated in hexadecimal, where each bit indicates the status of a digital output, that is, if the Bit0 is “0”, DO1 is inactive; if the Bit0 is “1”, DO1 is active, and so on up to DO5. Therefore, DOx active (1) means closed transistor or relay, inactive (0) means open transistor or relay.

PID Controller 5. Define digital input for the Manual/Automatic command: In order to execute the Manual/Automatic command in the PID controller, it is necessary to define which digital input will execute this command. In order to do so, program one of the parameters P0263 to P0270 in 22. Suggestion: program P0265 in 22 for the digital input DI3 to execute the Manual/Automatic command. 6.

PID Controller On the screen of Figure 13.3 on page 13-8 is observed a Setpoint of 20.0 bars on the secondary display, the process variable also at 20.0 bars on the main display and the output speed at 80 % on the bar. Figure 13.3: Example of HMI in the monitoring mode to use the PID regulator 13.5 PID PARAMETERS Below are described in details the parameters related to the PID controller. P0040 – PID Process Variable Adjustable Range: 0.0 to 3000.
PID Controller P0520 – PID Proportional Gain P0521 – PID Integral Gain P0522 – PID Differential Gain Adjustable Range: Factory P0520 = 1.000 Setting: P0521 = 0.430 P0522 = 0.000 0.000 to 9.999 Properties: Access Groups via HMI: Description: These parameters define the proportional, integral and differential gains of the function PID controller and must be set according to the application which is being controlled. Some examples of initial settings for some applications are presented in Table 13.
PID Controller In case the operation is in the Manual mode, the reference via HMI is set in parameter P0121. The value of P0525 is kept in the last value set (backup) even when disabling or powering down the inverter when P0536 = 1 (Active). P0526 – PID Setpoint Filter Adjustable Range: Factory Setting: 0 to 9999 ms 50 ms Properties: Access Groups via HMI: Description: This parameter sets the Setpoint filter time constant of the PID controller.
PID Controller Example: the pressure transducer operates at 4-20 mA for a band of 0 to 25 bars; setting of parameter P0528 at 250 and P0529 at 1. P0529 – Process Variable Indication Form Adjustable Range: 0 = wxyz 1 = wxy.z 2 = wx.yz 3 = w.xyz Factory Setting: 1 Properties: Access Groups via HMI: HMI Description: This parameter allows setting the form of indication of the PID process variable (P0040) and PID Setpoint (P0041). P0533 – X Process Variable Value Adjustable Range: 0.0 to 100.
PID Controller VP(%) Setpoint VP-reverse VP-direct P0535 P0535 t1 0 Time Figure 13.4: OK Setpoint band defined by P0535 According to Figure 13.4 on page 13-12, the condition imposed by P0535 depends on the type of action of the PID: direct or reverse. Therefore, if the PID is direct (P0527 = 0) the error must be smaller than P0535 for the inverter to go into the Sleep mode (Setpoint ok).
PID Controller y(k-1): PID previous output. Kp (Proportional gain): Kp = P0520. Ki (Integral gain): Ki = P0521 x 100 = [1/Ti x 100]. Kd (Differential gain): Kd = P0522 x 100 = [Td x 100]. Ta = 0.05 sec (sampling period of the PID controller). e(k): present error [SP*(k) – X(k)]. e(k-1): previous error [SP*(k-1) – X(k-1)]. SP*: Setpoint (reference), it may vary from 0.0 to 100.0 %.

Rheostatic Braking 14 RHEOSTATIC BRAKING The braking torque that may be obtained by the application of frequency inverters, without rheostatic braking resistors, varies from 10 % to 35 % of the motor rated torque. In order to obtain higher braking torques, resistors for rheostatic braking are used. In this case, the regenerated energy is dissipated in the resistor mounted outside the inverter.

Faults and Alarms 15 FAULTS AND ALARMS The problem detection structure in the inverter is based on the fault and alarm indication. In case of fault, the locking the IGBTs and motor stop by inertia will occur. The alarm works as a warning for the user of critical operating conditions and that may cause a fault if the situation is not corrected.
Faults and Alarms It is recommended that parameter P0156 (motor overload current at rated speed) be set at a value 10 % above the used motor rated current (P0401). In order to deactivate the motor overload function just set parameters P0156 to P0158 to values equal to or above two times the inverter rated current P0295. Figure 15.

Disable the ground fault or overload protections may damage the inverter. Only do that under WEG technical directions. 15.
Faults and Alarms NOTE! The DI2 is the only one that cannot be used as PTC input, because it has input circuit dedicated to frequency input (FI).

Faults and Alarms ATTENTION! An improper change of P0397 may damage the inverter. Only do that under WEG technical directions. 15.5 OVERCURRENT PROTECTION (F0070 AND F0074) The ground fault and output overcurrent protections act very fast by means of the hardware to instantly cut the output PWM pulses when the output current is high. Fault F0070 corresponds to an overcurrent between output phases, while fault F0074 indicates an overcurrent from the phase to the ground (PE).
Faults and Alarms NOTE! When this fault occurs, contact WEG. 15.12 FAN SPEED FAULT (F0179) This fault occurs when the inverter internal temperature is higher than the threshold to enable the fan (>50 ºC (>122 °F)) and the fan speed read is below 2/3 of the rated fan speed. The user should check if the fan is properly connected and not clogged with dirt. If the fan doesn’t start it should be replaced as soon as possible. 15.
