Description

Motor module Cross Reference to Related Applications The present application is based on and claims priority from japanese patent application No. 2020-154618 filed on 9/15 in 2020, the entire contents of which are incorporated herein by reference. Technical Field One or more embodiments of the present invention relate to a motor module that operates an in-vehicle device such as a power window (power window) mechanism mounted on a vehicle. Background For operating an in-vehicle device mounted on a vehicle such as an automobile, a motor module disclosed in WO-A1-2010/110112, for example, is used. The motor module is integrated with a motor as a power source of the in-vehicle apparatus, a mechanism for decelerating rotation of a motor rotation shaft, a sensor for detecting a motor rotation speed, a driving unit for driving the motor, a control unit for operating the driving unit to control driving of the motor, and the like. In addition to the above configuration, there are a motor module integrated with a memory storing information for operating the in-vehicle device, and a communication unit that communicates with another module or device via a network such as LAN or CAN built in the vehicle. For example, JP-A-2015-020647 and JP-A-2006-256547 disclose in-vehicle device control systems including such a motor module (slave device) and a management module (master device) that manages the motor module. The management module is configured with an Electronic Control Unit (ECU) including a control unit having a CPU or the like, a memory, a communication unit that communicates via a network of the vehicle, or the like, or a module having other functions. In order for the motor module to control the operation of the in-vehicle device, and for the management module to control the motor module, initial setting is required. Therefore, in JP-a-2015-020647, identification information of a slave device and a driver (software) for a master device to control the slave device are stored in advance in a memory of the slave device. At the initial setting, the slave transmits the identification information and the driver stored in the memory of the slave to the master via the network. When the master device receives the identification information and the driver from the device, the master device associates the identification information and the driver and stores the identification information and the driver in the memory. At the time of the subsequent operation, the master device transmits a control command to the slave device along with the identification information according to the condition indicated by the driver. The control command is received from the device, the operation of the main body unit such as the motor is controlled based on the control command, and the in-vehicle device is operated. Further, for example, JP-A-2006-256547 discloses a technique in which a slave determines identification information of the slave based on a voltage applied from another slave or a master connected via a network. Specifically, the resistance circuits provided in the plurality of slave devices are connected in series to an electric wire (the electric wire is connected to a power supply unit provided in the master device), and a voltage is applied from the power supply unit to the electric wire. Then, the slave device determines identification information of the slave device based on the divided voltage value of the resistance circuit of the slave device, and stores the identification information in the memory. Further, for example, WO-A1-2007/004617 discloses a technique in which a control unit separate from a motor learns information for controlling driving of the motor to cause a power window mechanism of a vehicle to safely perform a switching operation. Specifically, the control unit detects a driving state such as a rotational speed of the motor and a switching state of the window glass such as a switching position of the window based on a pulse signal generated by the pulse generator according to the driving state of the motor. When there is no foreign matter in the window, the control unit learns the pulse width of the pulse signal generated by the pulse generator according to the driving state of the motor and the rate of change of the pulse width, and stores the pulse width and the rate of change in the memory as parameter information (threshold value or the like) for the pinching (pin) determination. On the other hand, TW-U1-M400957, JP-A-2001-003639, JP-A-2017-210798, JP-A-2002-002293 and JP-A-2008-231878 disclose techniques of fine tuning (inching) a motor or a power window mechanism in the event of a malfunction, failure or the like in view of safety and convenience. Specifically, in TW-U1-M400957, the window glass may be displaced by a certain amount in the event of a motor-related failure. According to JP-a-2001-003639, in the event of disconnection in a window frame sensor, the closing operation of the window glass is
