*New features: | *New features: | ||
− | **Added Position feed-forward gain parameter | + | **Added Position feed-forward gain parameter [[PFF]] - helps to reduce overshoot in position control mode. In previous firmware, this value was fixed to 100%. |
− | ** | + | **Simulated encoder output from internal EXT connector (6 pin header) - useful with resolver systems where external [[controller]] needs encoder count |
**Homing with index pulse search is now possible with resolver feedback device (simulated index pulse at certain resolver angle(s)) | **Homing with index pulse search is now possible with resolver feedback device (simulated index pulse at certain resolver angle(s)) | ||
+ | **Added [[Torque mode application specific attributes]] (rotation angle limit & torque scaling by analog input) | ||
**Added support for ''direction'' input signal in [[PWM]] and Analog setpoint modes | **Added support for ''direction'' input signal in [[PWM]] and Analog setpoint modes | ||
**Identifies the reason why torque of motor is being limited (such as user limit or supply voltage limit). Shown in Granity Testing tab. | **Identifies the reason why torque of motor is being limited (such as user limit or supply voltage limit). Shown in Granity Testing tab. | ||
− | **[[SimpleMotion V2]] protocol updated | + | **[[SimpleMotion V2]] protocol updated: |
***added support for watchdog (stop drive if valid SM commands not arriving within predefined time period) | ***added support for watchdog (stop drive if valid SM commands not arriving within predefined time period) | ||
***calculation of setpoint commands via SM bus renewed (drive setpoint is a sum of phyiscal setpoint (step/dir, pwm, analog etc) and the setpoint from SM host (instant and buffered commands). If SM host sets absolute setpoint, then phyiscal counter (incremental types onle) are reset to zero.) | ***calculation of setpoint commands via SM bus renewed (drive setpoint is a sum of phyiscal setpoint (step/dir, pwm, analog etc) and the setpoint from SM host (instant and buffered commands).
