Вечер добрый!
Засветилась неисправность er134 на приводе M300-03400056A. Похожие устройства ATV61WD22N4A24, 3G3PV-A2037, VFD022EL21A установленные на вентиляции работают.
Решение нашел через майлру по запросу "psmn2r0-30yl" prom-electric.ru/media/PSMN2R0-30YL.pdf . Сгорел IGBT-module.
Успехов!

IN token packets to the endpoint, and the endpoint returns notifications as available. The endpoint descriptor’s bInterval field specifies the maximum latency between IN token packets. An endpoint that has no notification to return should return NAK on receiving an IN token packet. D evices that support the abstract control model must support the RESPONSE_AVAILABLE notification. However, if the device is a generic COM-port device that doesn’t connect to a modem that supports AT commands, the device will have no need for this notification and will return NAK on every IN token packet to the notification endpoint. The SERIAL_STATE notification is optional but recommended for devices with asynchronous serial interfaces. The notification sends the states of RS-232 344 Using Generic USB Controllers signals and other status information. In the notification, wValue = 0x0000, wLength = 0x0002, and the returned data has this format: Bits Field Description 15..7 -- Reserved. 6 bOverRun Received data has been discarded due to an overrun in the device. 5 bParity A parity error has occurred. 4 bFraming A framing error has occurred. 3 bRingSignal State of ring indicator RI . 2 bBreak Break state. 1 bTxCarrier State of data set ready DSR . 0 bRxCarrier State of carrier detect CD . Maximizing Performance Firmware and host-application programmers can do much to ensure efficient data transfers for CDC USB virtual COM-port devices. These are issues that effect the performance of device firmware: • Set wMaxPacketSize in the bulk endpoint descriptors to 64 recommended for full speed or 512 required for high speed. These sizes enable transferring the most data possible in each USB transaction. Plus, if a full-speed bulk endpoint’s wMaxPacketSize is less than 64, some USB host controllers UHCI type will schedule no more than one transaction per millisecond for the endpoint. • To transfer large amounts of data to the host as quickly as possible, use wMaxPacketSize data packets.
