67 / 73 page ![]() L6480 Programming manual Doc ID 023278 Rev 3 67/73 The GoMark command produces a motion to the MARK position performing the minimum path. Note that, this command is equivalent to the “GoTo (MARK)” command. If a motor direction is mandatory, the GoTo_DIR command must be used. The GoMark command keeps the BUSY flag low until the MARK position is reached. This command can be given only when the previous motion command has been completed (BUSY flag released). Any attempt to perform a GoMark command when a previous command is under execution (BUSY low) causes the command to be ignored and the NOTPERF_CMD flag to rise (Section 9.1.24). 9.2.14 ResetPos The ResetPos command resets the ABS_POS register to zero. The zero position is also defined as the HOME position (Section 6.5). 9.2.15 ResetDevice The ResetDevice command resets the device to power-up conditions (Section 6.1). Note: At power-up the power bridges are disabled. 9.2.16 SoftStop The SoftStop command causes an immediate deceleration to zero speed and a consequent motor stop; the deceleration value used is the one stored in the DEC register (Section 9.1.6). When the motor is in high impedance state, a SoftStop command forces the bridges to exit from high impedance state; no motion is performed. Table 61.
