Description
The VCTAB command is used for the definition /display of the VC table (velocity/current table). The VC table contains 8 velocity/current pairs (VCT entries).
A VCT entry can be activated either from the digital inputs or by an ASCII or SDO command.
When a VCT entry is activated, the velocity value that has been entered is taken as a digital velocity setpoint (only possible with OPMODE=0). The current value from the VCT entry is taken as the current limit.
With analog velocity setpoint provision (OPMODE=1), the velocity setpoint is ignored, but the current value is still used as the current limit.
The VC table is not saved in the serial EEPROM, but in the Flash EEPROM (motion task segment). For this reason, changes to the table entries can only be made while the output stage is disabled.
The VCTAB command can be used in one of three different forms:
- VCTAB nr vsetp ilimit
This command initializes the VCT entry nr with the velocity setpoint vsetp and the current limit ilimit.
nr <0 ... 7>
vsetp <-16000 RPM ... 16000 RPM>
ilimit <0 .... 100000 mA>
The command can only be used in this form while the output stage is disabled. - VCTAB nr
This command is used to output the contents of the VCT entry nr.
The output is made in the format VCTAB nr vsetp ilimit. - VCTAB
This command is used to output the contents of the VCT table via the RS232 interface.
The output consists of 8 lines in the following form:
VCTAB nr vsetp ilimit
