正值表示正向旋转
负值表示反向旋转。驱动过载操作理论以下讨论假设IT曲线不会随脉宽调制（PWM）载波频率或驱动输出频率而改变。驱动器有三个额定电流值；连续电流额定值、1分钟电流额定值和3秒电流额定值。通常，1分钟的额定值将接近连续额定值的110%，而3秒的额定值则接近持续额定值的150%。这可能因驱动器而异，以优化每个帧大小的性能。在以下示例中，1分钟评级为110%，3秒评级为150%。开环电流限制驱动器可以热允许102.5%。1分钟电流额定值假设占空比为1分钟，然后在100%时为3分钟。这导致平均电流为102.5%。HIM控制的双极参考？HIM方向按钮启用是由于HIM提供（+）或(命令信号。启用否对电机方向没有影响。方向由Par 40[选定SpdRef]的符号确定。禁用是由于HIM提供正向或反向[Applied LogicCmd]位，更改电机方向。禁用无由于HIM提供正向或反向[Applied LogicCmd]位而改变电机方向。

A positive value indicates positive rotation
Negative values indicate reverse rotation. The following discussion of drive overload operation theory assumes that the IT curve will not change with the pulse width modulation (PWM) carrier frequency or drive output frequency. The driver has three rated current values; Continuous current rating, 1 minute current rating and 3 second current rating. Generally, the rating for 1 minute will be close to 110% of the continuous rating, while the rating for 3 seconds will be close to 150% of the continuous rating. This may vary by drive to optimize performance per frame size. In the following example, the 1-minute rating is 110% and the 3-second rating is 150%. The open-loop current limiting driver can allow 102.5% thermal allowance. The 1-minute current rating assumes a duty cycle of 1 minute and then 3 minutes at 100%. This results in an average current of 102.5%. Bipolar reference for HIM control? The HIM direction button is enabled because HIM provides (+) or (command signal. Enabling or not has no effect on the motor direction. The direction is determined by the symbol of Par 40 [Selected SpdRef]. Disabling is because HIM provides a forward or reverse [Applied LogicCmd] bit to change the motor direction. Disabling does not change the motor direction because HIM provides a forward or reverse [Applied LogicCmd] bit.

This results in an average current of 102.5%. Typically, the 60 second rating of the drive is 110% continuous current and the 3 second rating is 150% continuous current. Under normal operating conditions, the open-loop function sets this current limit to a short-term (three second) rating. If the function detects an overload, the limit is reduced to a continuous level. If the function is at the continuous level limit, it may be below the motor current limit. After a period of time (usually one to three minutes), the function returns the limit to the short-term rating.
