In order to stop the unrequested messages sent by the drive to the host when in PVT mode, the user need to set the PVTSENDOFF variable to 1. Add the line "PVTSENDOFF = 1;" at the beginning of his program and the drive will no longer send the PVTSTS to the host.
The current, speed or position controllers parameters can be changed online through the following parameters: 1. Current controller The proportional gain components Address KPI 0x0271 SFTKPI 0x0272 The formula used to compute the Kp parameter is: Kp = KPI / 32767 * 2^SFTKPI where: KPI = 0 .... 32767 SFTKPI = 0 ... 14 The integral [...]
The PVT buffer is stored in the RAM memory of the drive. Apart from storing the PVT points, the RAM memory contains also the data acquired with the Logger and the CAM tables. The amount of memory available and the addresses of various memory sections depend on the drive and can be visualized in Memory [...]
The iMOT intelligent motors use a magnetic encoder that outputs quadrature signals but additionally, it can also output the motor absolute position, on one mechanical turn. The absolute position is saved in the controller RAM memory, at the address 0x222 and goes from 0 to 4096. To read it, the following TML code sequence can [...]
The drive supply voltage can be read through the AD4 parameter (uint@0x240) and the drive temperature through the AD7 parameter (uint@0x243). The returned values are expressed in IU (drive internal units). To convert them to volts and respective to degrees Celsius, the following scaling factors needs to be applied. 1. Drive Supply Voltage Voltage_measured [V] = (VdcMaxMeasurable/65520) * Voltage_measured [IU] Where VdcMaxMeasurable is [...]
The hexadecimal value of a negative decimal number can be obtained starting from the binary value of that decimal number positive value. The binary value needs to be negated and then, to add 1. The result (converted to hex) represents the hex value of the respective negative decimal number. The example below shows how to [...]
In TML, the fractional numbers (usually stored in 32 bits fixed variables) are represented (in hex) using the "16.16" format. According to this format, to get the hex value of a fractional number, the first step is to multiply the fractional number with 65536. The result will be rounded or truncated and cast to a [...]
