braking is 15 sec and the braking resistor signal is not output from the
inverter after the 15 sec period has expired. The time until braking
resistance is available again after continuous use of braking resistance
for 15 seconds is calculated as below.
If the braking resistor usage rate is set to 0%, braking resistance can be
used without usage rate restriction. However, precaution is necessary
since there is risk of fire if the braking resistance usage is higher than
the power consumption of braking resistance.
An example of braking resistor set up is as follows:
[Example 1]
[Example 2]
• T_acc: Acceleration time to set frequency
• T_steady: Constant speed operation time at set frequency
• T_dec: Deceleration time to a frequency lower than constant speed
