Parameters
M-Max Series Adjustable Frequency Drive MN04020003E—October 2013 www.eaton.com 73
Digital Inputs, continued
The binary connection of three digital inputs enable calling seven fixed
frequencies (eight fixed frequencies if parameter P6.2 = 0 is set)
The limitation of the fixed frequencies is done based on parameters
P6.3 (minimum frequency) and P6.4 (maximum frequency)
The switch between the individual fixed frequencies is done with the
acceleration time and deceleration times in P6.5 and P6.6
