The delay time is used to debounce noisy signals that could cause the digital terminals to malfunction. Over-Torque detection enabled during constant speed operation. Refer to the Basic Wiring Diagram. When we are assisting with selection of our Variable Frequency Drives we look at your application, is it being used for Constant or Variable Torque Standard Pumps are considered a Variable Torque ,. After a parameter value has been set, the new value is automatically stored in memory. Overheating Remove any foreign objects from the Heat sink temperature too high heatsinks and check for possible dirty heat sink fins. Without this basic knowledge base, it will be difficult to make the installation and operation of the device successful.
Default set ting is 60 Hz. In addition to signals of 0 to 10V and 4 to 20mA, the popular voltage signals also include signals of 0 to 5V, 4 to 20mA or any value under 10V. The sensor that is connected to the input generates a large signal 10V or 20mA at high pressure or flow. Please choose the applicable one from below, depending on the plate thickness t. The default value settings simplify the start-up procedure. Explosion-proof Ex motor: Needs to be installed in a safe place and the wiring should comply with the Ex requirements. Daily Inspection: Basic check-up items to detect if there were any abnormalities during operation are: Whether the motors are operating as expected.
When receiving a new there are some basic steps that must be taken after the main wiring installation. Inductance mH Fundamental continuous Amps 3% impedance 5% impedance Amps 18. Gear reduction motor: The lubricating method of reduction gearbox and speed range for continuous operation will be different and depending on brand. Torque boost too high: Decrease the torque compensation setting in Pr. The four most recent faults can be read from the digital keypad or communication. Please consult the designated manufacturers manual for any other information regarding wiring and parameter settings for external signal controls, switches, input voltages or currents. .
Maximum output voltage is 70% of the normal output voltage. Ye s Can ac celerati on Can dec elerati on time be made l onger? Display the estimated value of torque in Nm as it relates to current. Over-current during Acceleration Time too short: Increase the acceleration Acceleration Time. Thank you for your interest in Marshall Wolf Automation and good luck with your programming! Make sure that the ventilation holes are not obstructed. Attained Preliminary Count Value Active when the counter reaches Preliminary Count Value. When the brake resistor heats up, the resistance would increase with temperature, and brake torque would decrease accordingly. Operation status is not changed even if operation command source Pr.
Negative slopes are used in applications for control of pressure, temperature or flow. See Chapter 2 for definition of direction of rotation. The parameter settings are: Pr. These components are especially sensitive to static electricity. Nearly 40% of the total energy used by indoor swimming pools. The whole scale of the potentiometer can be used as desired.
Keep in mind that some variable frequency drive manufacturers have parameters that might have to be unprotected to have access to these higher level numbers. No error message is displayed. Operation status is not changed even if operation command source Pr. Connect shielded wire to E only. The actual value stored in the specified parameter.
Decel time 2 Accel time 3 01-12 01-18 Decel time 3 Accel time 2 01-19 01-11 Decel time 4 Accel time 1 01-21. During Auto acceleration the torque is automatically measured and the drive will accelerate to the set frequency with the fastest acceleration time and the smoothest start current. Keep Running when Frequency Command is Lost Related Applications Purpose Functions. How do we do that? Terminals for external Base Block control. In continuous manufacturing processes, the cost of the energy consumed by a particular pump motor is normally far in. We can instruct qualified personnel on the basics of drive technology, train them on the efficient operation and monitoring of power converters, and then teach them how to analyze and rectify malfunctions. Or power cut, Restart after reset including momentary power loss Check if there is any malfunction Change defective component component or disconnection and check connection.
When Pulse Generator Encoder is Open Collector type, please refer to following wiring. Read the manual and locate the parameters for each of items listed above so that the information can be confirmed to be the same as the factory default parameter or modified for the specific motor as required by the factory manual. When parameter value Forced Stop N. Inductance mH Fundamental continuous Amps 3% impedance 5% impedance Amps 0. Take into consideration the safety of the environment when installing the brake resistors. This parameter should be set at a value to ensure that any residual regeneration voltage from the motors on the output has disappeared before the drive is activated again.
These six parameters should be set as follows Pr. A motor with high inertia will take a long time to stop completely. Due to strict technical requirements, it can be difficult to find qualified service providers for commissioning services — and training in-house employees can be costly. Response Original speed Desired new speed Desired speed setpoint Actual speed Deviation error output Proportional circuit Integral circuit Derivative circuit. Here are the most basic steps in the programming process of. Refer to Appendix A for rated input current 1-phase 3-phase Recommended Recommended Recommended.
After the over- torque is detected, stop running. For further information on this please email our tech support team at and they would be happy to assist you. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands. Always refer to the manufacturers manuals for any and all specific programming details and warnings. Overheat Warning for Heat Sink. Once a fault is detected, the corresponding protective functions will be activated.
