Acs880 run in tandem
Dear all,
we set up inverter acs880 to run hoist motor.
2 inverter control 2 hoist. And we control inverter via profibus by plc.2 inverter communicate via D2D link.
when run in tandem mode, 2 hoist start at same time but not stop at same time, master hoist stop first ( look like emergency stop), and follower hoist still ramp down normally.
in this case, what need to do?
thank you

Hi
a question that perhaps seems useless, but I need to do ..... have you checked that the programming of the two inverters is absolutely the same, as far as deceleration ramps and the stop mode are concerned? In particular the parameters of group 21 - 01 up to 07?
