所需的扭矩参考。摩擦产生的分离扭矩总是大于摩擦产生的运行扭矩。此参数以每单位为单位，因此值1等于100%电机扭矩。参数143[FricComp Slip]设置扭矩水平，以在实现分离后保持非常低的速度。同样，由于摩擦而非常接近0速度运行所需的扭矩将大于由于摩擦而以更高速度运行所需要的扭矩。此参数以每单位为单位，因此值1等于100%电机扭矩。参数144[FricComp Rated]设置保持电机以基本电机速度运行且无过程负载所需的扭矩。此参数以每单位为单位，因此值1等于100%电机扭矩。摩擦补偿算法假定[FricComp Slip]和[FricCompRated]之间的摩擦为线性或粘性分量。摩擦补偿块计算摩擦所需的扭矩，如参数145[FricComp TorqAdd]所示。[FricComp TorqAdd]与惯性补偿块的输出和速度参考回路产生的扭矩相加。总扭矩进入扭矩选择块（更多信息，请参阅第175页的扭矩参考）。

43[S Curve Spd Ref]。 Speed reference is required because the torque required for friction is greater near 0 speed than at higher speeds. Enable friction compensation by setting the 11th bit "Frict Comp" of parameter 151 [Logic Command] to "1". Value description 0 Encoder 0 1 Encoder 1 2 Sensorless 3 Reserved 4 Motor simulation 5 FB selection port 0 6 FB selection port 1 Automation publication PFLEXRM002DENE August 65, 2013 Detailed drive configuration and operation Chapter 1 Parameter 141 [FricComp setting] is used to configure the friction compensation algorithm. This is a 3-digit compressed word. Each number can select 10 levels. • The least significant digit sets the speed threshold at 0.0005 pu speed intervals. • The next (middle) number sets the hysteresis band for the "unit" number at 0.0005 pu speed intervals. • The most significant digit sets the time steps from sticking to sliding, each of which is 0.002 seconds. Example: Fsetup=524 means that there are five time steps between sticking and sliding, each of which is 0.002 seconds. Duration: 2 lagging counts or 0.001 pu speed (each count is 0.0005 pu speed), 4 counts or 0.002 pu speed is the trigger threshold (each count is 0.0005 pu speed).
Set breakaway speed
Required torque reference. The separation torque generated by friction is always greater than the running torque generated by friction. This parameter is in units per unit, so the value 1 equals 100% of the motor torque. Parameter 143 [FricComp Slip] sets the torque level to maintain a very low speed after separation is achieved. Similarly, the torque required to run very close to zero speed due to friction will be greater than the torque required to run at a higher speed due to friction. This parameter is in units per unit, so the value 1 equals 100% of the motor torque. Parameter 144 [FricComp Rated] sets the torque required to keep the motor running at base motor speed without process load. This parameter is in units per unit, so the value 1 equals 100% of the motor torque. The friction compensation algorithm assumes that the friction between [FricComp Slip] and [FricCompRated] is a linear or viscous component. The friction compensation block calculates the torque required for friction, as shown in parameter 145 [FricComp TorqAdd]. [FricComp TorqAdd] is added to the torque generated by the output of the inertia compensation block and the speed reference circuit. The total torque enters the torque selection block (for more information, see Torque Reference on page 175).
