missing coil checks on the auxiliary driver output.When this parameter is set to “On,”the controller senses the voltage at the auxiliary driver output(Pin 18)to confirm that the auxiliary contactor coil is properly connected. If the criteria for this test are not met, the controller will inhibit operation and issue a fault.This test is not performed if the aux check parameter is set to“Off.”

NOTE:The aux check parameter is applicable only if the accessory driver enable specified“On.”The accessory driver enable is a factory-set parameter,and is described in Section 4.

REV DRVR CHECK

The reverse signal open check parameter defines whether the controller per-forms missing load checks on the reverse signal driver output.When this parameter is set to“On,”the controller senses the voltage at the refiverse signal driver output(Pin 19)to confirm that the reverse signal driver load is properly connected. If the criteria for this test are not met, the controller will inhibit operation and issue a fault.This test is not performed if the reverse signal open check parameter is set to“Off.”

NOTE:The reverse signal open check parameter is applicable only if the accessory driver enable specified“On.”The accessory driver enable is a factory-set parameter,and is described in Section 4.

EM BRAKE DELAY

The electromagnetic brake delay parameter is applicable only if the accessory driver enable specified“On.”The accessory driver enable is a factory-set parameter,and is described in Section 4.

The electromagnetic brake delay parameter can be set to delay engaging the electromagnetic brake for a specified period of time after the controller senses that braking completed and the vehicle 0.1 second intervals.

EM BRAKE CHECK

The electromagnetic brake open check parameter defines whether the controller performs missing coil checks on the electroma gnetic brake driver output. When this parameter is set to“On,”the controller senses the voltage at the electromagnetic brake driver output(Pin 20)to confirm that the electromagnetic brake coil is properly connected. If the criteria for this test are not met,the controller will inhibit operation and issue a fault.This test is not performed if the electromagnetic brake open check

parameter is set to“Off.”

NOTE:The electromagnetic brake open check parameter is applicable only if the accessory driver enable specfied“On.”The accessory driver enable is a factory-set parameter,and is described in Section 4.

CONT HOLDING

The contactor ,auxiliary,reverse,and electroma gnetic brake drivers.This parameter is adjustable from 20% to 100% of the battery voltage, in 2% increments. It allows the OEM to reduce the average applied voltage so that a contactor coil or other load that is not rated for the full battery voltage can be used. For example,contactor coils rated for 12V could be used with a 36V system if the contactor be set lower than the rated contactor coil voltage,as long as it is set conditions the vehicle will be subjected to.Low settings minimize the current required to power the coil,thereby reducing coil each driver must allow operation at the set addition,the loads on each driver must be compatible with a PWM signal(if the parameter is set to a value less than 100%),as the output is pulse width modulated.

CONT PULL IN

The contactor pull-in voltage parameter sets the peak voltage applied to the loads connected to the main,auxiliary,reverse and electromagnetic brake drivers.Typically these loads are contactor coils.The pull-in parameter allows a the driver first turns on,to ensure contactor closure.After 0.1 second,the driver voltage drops to the value specified by the contactor 2%increments.

VOLTAGE

The battery voltage parameter sets the overvoltage and undervoltage protection thresholds for the electronic system.This parameter determines when regen should be cut back to prevent damage to batteries and other electrical system components due to overvoltage.Similarly,the undervoltage threshold protects systems from operating at voltages below their design thresholds.This will ensure proper operation of all electronics whenever the vehicle is driven.The battery metersvoltage parameter can be set from 2 to 7,and should always be set to the system’s nominal battery pack voltage:

在故障分类的格式中，这两个断层线共同确定的四个故障类别。表格4描述就是4个类别的故障，表明该国每一类的两个产出，并列出了当四个类别故障信号传输时，可能会出现的故障。

主要控制中断

主接触器驱动联锁参数允许制造商定义一个双开关要求操作汽车。当此参数设置为“ 开”时，控制器要求KSI输入（引脚1 ）和联锁输入（引脚2 ）两种输入，撤出高压区（至B + ）之前 ，控制器将从事主要接触工作。主要接触后会打开联锁开关和主要开放延误测试如果这个参数设定为“关” ，只有KSI参与输入所需的主要接触。

主开放延时

主要接触延迟参数只适用于主接触器驱动联锁参数设定为“开”。联锁开关打开后，延迟参数可以设置主要接触保持关闭一段时间。延迟时间可从零到40秒编程，时间间隔为1秒钟。 延迟也是有益的，从防止不必要的循环的主要联系人和维护辅助功能来看，如转向助力泵电机，在刹车系统已启动或驾驶者已离开座位之后在很短的时间起作用。

44页 主要检查

主要线圈检查参数限定是否控制器执行丢失线圈检查，以确保主要的接触已正确关闭。当这个参数设定为“开” ，该控制器感应电压的主要动力输入（引脚17 ） ，以确认主要接触线圈是正确连接，并测试，每次都这样做。如果标准或者这些测试不符合要求，控制器将抑制运作，并发出错误提示. 如果主要参数设置为“关闭”所有的检测系统将不工作。

焊缝检查

主要接触焊接检查参数限定是否控制器试验的主要接触人，以确保不是关闭焊接的焊缝检查。如果参数设置为“开” ，进行检查， 但关键开关首先是参与，并且每次主要控制器的命令是开。如果参数设置为“关闭” ，检查将不能进行。

延时辅助

联锁开关打开后，辅助驱动延迟参数可以设置为允许 …… 此处隐藏：4849字，全部文档内容请下载后查看。喜欢就下载吧 ……
