The nominal resolution is given by Pr 7. The number of encoder lines per revolution defined by Pr 3. There is no parameter to display the motor temperature. This trip can be disabled so that the drive can run by setting bit 3 of Pr 10. Servo: Quadrature incremental encoder with commutation outputs, with or without marker pulse 4, Fd. When this parameter is set the 'Drive ok' indication is not cleared on a trip if an auto-reset is going to occur.

Connect the motor thermistor between 0V and terminal B7. The other rows give the following information. This clock may be used for time stamping the trip log if Pr 6. When a manual reset occurs the auto reset counter is reset to zero. These bits are for control by digital inputs such that ramp rates can be selected by external control. Onboard Application Lite Ladder Program is installed but stopped.

This enables the user to perform any required initialisation every time the ladder diagram is run. After a modification to this parameter, the destination is only changed when a reset is performed. If the feedback is not filtered it is possible the output of the speed controller will be a square wave that changes between the current limits causing the integral term saturation system to malfunction. If a non-valid parameter is programmed, then the digital output will remain in the inactive state. The rated active current is used extensively to control the drive, and the magnetising current is used in vector mode Rs compensation. The maximum measurable value for a particular drive size can be calculated from the following formula.

This chapter describes the implementation character Ctl D is returned. This is particularly important if the encoder is selected for speed feedback with Pr 3. Generally the result is rounded down to the nearest unit, but other rounding effects may occur depending on the internal scaling of the particular source function. The reason for the error is stored in Pr 15. In torque control mode the current demand is limited by the active current limit.

Table 9-2 Key to parameter coding. The product identifier is written to the card. The motor can only be restarted if the enable or run command is removed and then re-applied or if the drive is tripped, reset and then given a run command. Ramp rate selection by parameter Pr 1. Current limit operation The current limits will normally operate with an integral term only, particularly below the point where field weakening begins. This parameter can only become active if mains loss ride through or mains loss stop modes are selected see Pr 6. The parameters stored in the encoder are in two categories: motor object parameters, and performance object parameters.

Please call or email us for availability. Wait for brake apply frequency 5. In all of the settings below, the status relay is set up as the drive healthy relay. So if the parameter value is 1510, fast cyclic data is set every 10ms and slow every 150ms. This feature is not available when absolute mode is selected Pr 13.

However in most cases it is not necessary as each input is automatically scaled such that for 100. A check should be carried out before each word is written to ensure that the parameter is zero i. As the torque level is reduced the measurement is likely to be affected by cogging and the results may not be accurate. If an analog input is used the absolute accuracy is further limited by the absolute accuracy and non-linearity of the analog input. The portable software class which implements this protocol is also defined.

Onboard Application Lite Ladder Program is installed and running. The position feedback initialised parameter Pr 3. The drive takes action on the command when the user exits the parameter edit mode. Setting it to 1 allows negative outputs also -100. If the scan time is greater than the maximum value which may be represented by this parameter the value will be clipped to the maximum value. If a value of 12001 is written to Pr x. Simple installation and configuration making it easy to use but it has the functions required to solve complex applications.

It should be noted that a trip can only occur when the drive is not tripped or is already tripped but with a trip with a lower priority number. For operation of this mode see Pr 4. This ensures that defaults are used for this menu if the saved parameters are from a software version which did not include this menu. The fast update rate is only possible provided the conditions given below are met. This does not cause save power down save parameters to be saved at this point. . Processor outputs is drawing too much current.

Only bit parameters can be programmed into these inputs. The setting of this parameter configures the terminal for the required mode. The minimum slave response time is times for example, at 19200 baud the minimum silent period is 2ms. Once the switching frequency has been reduced the drive determines when the switching frequency can be switched back up again. During this period the frequency reference is held constant Pr 2. Bit 7 of the control word has no effect on this function. The variable selector output gives 0% if the rectifier is ok otherwise it gives 100%.
