Page Chapter 4 Parameters resistor value Page Group 8: Special Parameters It is recommended to start with a low DC Brake Current Level and then increase until proper holding torque has been achieved.
Under such circumstances, DC Brake can be used to hold the load in position before setting it in motion. DC Brake during stopping is used to shorten the stopping time and also to hold a stopped load in position.
Page Output frequency Output voltage V Fig 1:B. Page Chapter 4 Parameters When momentary power loss is detected, the AC motor drive will block its output and then wait for a specified period of time determined by Pr. This parameter should be set at a value to ensure that any residual regeneration voltage from the motor on the output has disappeared before the drive is activated again. Page These parameters set the Skip Frequencies.
It will cause the AC motor drive never to remain within these frequency ranges with continuous frequency output. These six parameters should be set as follows Pr.
Therefore, when the AC motor drive is used without AVR function, the output voltage will be the same as the input voltage. By using this parameter, it will improve this situation greatly. The drift current zone of the high-power motors is usually in the low frequency area.
The RS master then controls each AC motor drive according to its communication address. Page Time-out Detection For example, 64 Hex. Communication Protocol 3. Page 1 03H: multi read, read data from registers. Example: writing data H to register H. AMD address is 01H. For example, reading 1 word from address H of the AC drive with address 01H. High byte of H is number of decimal places of H.
Illegal data address: The data address received in the command message is not available for the AC motor drive. Select input terminal accordingly.
Make sure this parameter setting does not conflict with the setting for Pr. Page When P is greater than 1, it will decrease the deviation and get the faster response speed. But if setting too large value in Pr.
NOTE The parameter can be set during operation for easy tuning. Page Chapter 4 Parameters This parameter defines an upper bound or limit for the integral gain I and therefore limits the Master Frequency. This parameter can limit the Maximum Output Frequency.
When frequency reaches wake up frequency, AC motor drive will accelerate from Pr. This parameter is used only for display and has no relation with Pr. Page Example: suppose that the set point of constant pressure control of a pump is 4kg, Pr. It means that deviation is 0. Page Chapter 4 Parameters Example: suppose that the set point of constant pressure control of a pump is 4kg, Pr.
