To switch between the two sets, a frequency threshold can be defined. A logic input may also be configured for ramp switching; see page The ramp profile for acceleration and deceleration is the gradual change of the output frequency from a speed reference following a linear or predetermined ratio that enables the ramps to be given an S- or U- shaped profile.
They are particularly suited to applications involving materials handling, packaging, and personnel transportation. U-shaped ramp profiles are ideal for pumping applications installations with centrifugal pumps and nonreturn valves because they improve control over valve operation. A torque limit can be implemented in three ways on constant torque rated products:.
This parameter can be used to limit the maximum motor current. Refer to the drive controller rating table for continuous current ratings and associated switching frequency. ATV58 TRX drive controllers have an automatic feature that is used if the drive controller is intermittently used at the high end of its temperature rating and HF1 or HF2 switching frequency type is programmed. A higher switching frequency will produce a waveform with less harmonic distortion and allow the current regulator in the drive controller to perform better.
Cable lengths greater than feet m may require adjusting the switching frequency to lower settings to reduce the transmission line phenomena that tends to develop in long conductors. When this parameter is enabled, the switching frequency is randomly modulated to avoid audible resonance from the motor. This parameter is useful in applications where audible motor noise is undesirable. This function is enabled when the Variable Torque macro-configuration is selected.
When the reference speed is attained, the drive controller begins lowering the voltage applied until the current begins to rise. It operates at this point until the speed reference is changed. This parameter is useful for saving energy in all variable torque applications. This function is available in variable torque mode and if the Energy Economizer function is disabled.
This function is available in variable torque mode, and provides for the automatic adaptation of the current limit according to the speed to avoid a motor overload fault. It is used in applications involving fans where the load curve of the fan changes with the air density, as shown in the graph to the left. This parameter should be enabled when using special motors such as synchronous permanent magnet motors, synchronous wound field motors, or synchronous reluctance motors.
This parameter should also be enabled when one drive is used to control multiple motors in parallel. See the Thermal Protection of Motor below for more information. This parameter can also be used in testing when a very small motor is used only to verify proper operation of a drive system wiring and control.
This function provides indirect thermal protection of the motor by continuous calculation of its theoretical temperature rise. For applications using self-cooled or force-cooled motors, the microprocessor calculates the theoretical temperature rise of the motor using the following elements:. NOTE: When the drive controller de-energizes, the I 2 t calculation is saved and the cooling effect is calculated. This function may also be used for specialized applications.
Thermal protection may be customized in the fault configuration menu for:. In these applications, provide direct thermal protection using PTC thermistor probes built into the motor. This function provides thermal protection of the motor. The probe break and probe short-circuit faults are monitored. This function provides direct thermal protection via a thermistor affixed to the heatsink, thus ensuring component protection even in the case of faulty ventilation or excessive ambient temperature.
When an overtemperature condition is sensed, the controller will fault on drive overtemperature. Drive control parameters can be viewed and modified only when the access locking switch on the keypad display is in the total unlock position see page They can be modified only when the motor is stopped. The drive controller is factory-configured for two-wire control.
The two-wire control function controls operation direction using maintained contacts. Depending on whether one or two directions of operation are required by the application, one or two logic inputs must be assigned to this function. An example of wiring for two-wire control is shown to the left.
Three operating modes are possible:. The three-wire control function controls operation and stopping direction using momentary contacts. Depending on whether one or two directions of operation are required by the application, two or three logic inputs must be assigned to this function. An example of wiring for three-wire control is shown to the left.
Three-wire control is appropriate for all types of applications with one or two operating directions. This function disables reverse operation. Applications such as those involving pumps, fans, or other applications where reverse operation may cause mechanical damage may require reverse to be disabled.
This parameter allows Analog Input 2 AI2 on the drive controller to be redefined to accept a range of signals. The input can be configured for 0 to 20 mA, 4 to 20 mA, or the minimum value X and maximum value Y can be user assigned by programming X and Y with 0.
Reverseacting operation can also be configured. For example, 20 to 4 mA, where 20 mA equals low speed and 4mA equals high speed. When this parameter is set to Yes, the drive controller can be controlled by the keypad. The factory default is No. In this mode of operation, the speed reference is entered in hertz or in customer defined units by using the keypad up or down arrow keys. This parameter allows the keypad STOP key to remain active even if the drive is being commanded via the terminal strip or a serial connection.
The factory default is Yes. If set to No, the keypad STOP key will not be active and the drive controller will not stop when it is pressed. This parameter is used to set the address when controlling the drive controller by a Modbus device via the RS port. The range of addresses is 0 to The factory setting is 0, indicating that the drive controller is not being controlled via the RS port.
This parameter can be used to reset the watt-hour meter or the run time meter back to zero. Selecting a macro-configuration automatically assigns the inputs and outputs to functions suitable for the application. Welcome to ManualMachine.
