官方故障排除步骤
Message value: Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: Only for separately excited sy nchronous motors (p0300 = 5): The current open-loop/closed-loop c ontrol mode is I/f control (open-l oop) with a fixed current (p1300 = 18). The speed is entered via the setpoint channel and the cu rrent setpoint is given by the minimum current (p1620). It must be ensured that in this mode, the control dy namic performance is very li mited. This is the reason that longer ramp-up times should be set fo r the setpoint speed than for normal operation. See also: p1620 (Stator current, minimum) Remedy: Select another open-loop/closed-loop control mode See also: p1300 (Open-loop/closed-loop control operating mode)
