组 21 启动/停车 预励磁时间 30 ms ... 10000 ms 2 CONST MAGN TIME 启动特性选择 CNST DCMAGN 1 START FUNCTION 描述 范围/单位 参数 Conditions during motor ON-order Duration of pre–magnetising 1CNST DC MAGN本参数不能改动！即设为恒定励磁模式。如果电机处于停止状态时这是一种最快的启动方式。 This parameter cannot be altered. Sets the constant magnetising mode. This is the fastest starting method if the motor is at a standstill 2 CONST MAGN TIME 在恒定励磁模式下定义的励磁时间,电机的额定功率值(kW)乘以7就可得出该参数的近似值 Defines the duration of the pre-magnetising in the constant magnetising mode. An approximate value for this can be calculated as the motor nominal power in kW multiplied by 7 组 27 制动斩波器 制动斩波器控制模式Brake chopper control mode AS GENERATOR; COMMON DC 6 BC CTRL MODE 最大连续制动功率Maximum continuous brake resistor power 0.00 … 10000.00 kW 5 MAX CONT BR POWER 制动电阻时间常数Brake resistor time constant 0.000 … 10000.000 s 4 BR THERM TCONST 制动电阻电阻值Brake resistor resistance value 0.00 … 100.00 ohm 3 BR RESISTANCE 制动电阻过载保护功能Brake resistor overload function NO; WARNING; FAULT 2 BR OVERLOAD FUNC 制动斩波器控制Brake chopper control OFF; ON 1 BRAKE CHOPPER 描述 范围/单位 参数 1 BRAKE CHOPPER 激活制动斩波器的控制。Activates the brake chopper control OFF 制动斩波器的控制无效。Brake chopper control is inactive ON 制动斩波器的控制有效。注意：确认制动斩波器和电阻器已安装，并且过电压控制为关闭状态 Brake chopper control is active. NOTE: Ensure that the brake chopper and resistor are installed and the overvoltage control is switched off 2 BR OVERLOAD FUNC 激活制动电阻器的过载保护功能。与之有关的用户可调变量为参数 27.03，27.04 和 27.05。 Activates the overload protection of the brake resistor. The user-adjustable variables are parameters 27.03, 27.04 and 27.05 NO 过载保护无效。Overload protection is inactive WARNING 过载保护有效。如果传动单元检测到过载，它就会产生一个警告信息。 Overload protection is active. If the drive detects an overload, it generates a warning FAULT 过载保护有效。如果传动单元检测到过载，它就会故障跳闸 Overload protection is active. If the drive detects an overload, it trips on a fault. 3 BR RESISTANCE 定义制动电阻器的电阻值 Defines the resistance value of the brake resi
