temeteron Posts: 3 Rating: (0)	i have a mm430 and i want to contol the frequency(up,down) by two digital inputs. i set p1080[0]=15Hz (Min. frequency ) and p1082[0]=40Hz (Max. frequency) but when mm430 reaches then lower limit and there is still command to decrease the frquency the actual frequency stays at 15Hz but the internal setpoint still reduced so then when it has command to increase the frequency i have to wait until the internal setpoint reach the actual frequency to increase and the opposite for the max frequency Best regards temeteron
