Functions
*1. If the b131 set value is lower than the incoming voltage or equivalent, the motor may not be stopped.
*2. When b130 = 01, PI control works to keep the internal DC voltage constant.
•Though quicker response is expected with a larger proportional gain (b133), control tends to be divergent
and may easily lead to a trip.
•Response also becomes quicker with a shorter integral time (b134), but if too short, the same situation may
occur.
<Group C: Multi-function Terminal Function>
The RX has eight input terminals [1], [2], [3], [4], [5], [6], [7], and [8]; five open collector output ter-
minals [11], [12], [13], [14], and [15]; one relay output terminal [AL2] and [AL1] (SPDT contact); two
analog output terminals [AM] and [AMI]; as well as one digital output terminal [FM].
Multi-function Input Selection
•You can use the following functions by allocating them to any of multi-function inputs 1 to 8.
To allocate the functions, set the following data in C001 to C008. For example, C001 corresponds
to input terminal 1.
•The same two functions cannot be allocated to the multi-function input terminals. If you attempt to
allocate the same two functions to the terminals by mistake, the terminal where you allocated the
function last takes precedence. The previous data is set to "no (no allocation)", and the terminal
function is disabled.
•After allocating functions to terminals 1 to 8, make sure that the function settings have been stored.
