How to disable the transmission of PVT status to the host

2018-09-11T14:26:29+00:00

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.

PVT buffer location and size

2023-02-14T15:34:53+00:00

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 [...]

Absolute position reading on the iMOT intelligent motors

2018-09-11T14:22:27+00:00

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 [...]

TML instructions list

2024-05-27T13:29:27+00:00

TML (short from Technosoft Motion Language) is a high-level motion programming language built for Technosoft intelligent drives and motors. It allows building complex motion applications locally, on each drive, leaving only the high level of motion application on the master device (EtherCAT / CANopen / custom made). The TML instruction code consists of 1 to [...]

Scaling factors for the Drive Supply Voltage and Drive Temperature parameters

2018-09-11T14:21:42+00:00

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 negative numbers representation in hex

2023-02-14T15:32:32+00:00

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 [...]

Fractional numbers reperentation using the 16.16 format

2018-09-11T14:20:53+00:00

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 [...]
