*1 Set S1-54 to S1-56 = 0 [Disabled] when you do not use the brake sequence.
Note:
• When the 3 motors are used, a protective function set in L1-01 [Motor Overload (oL1) Protection] is applied to motor 1 and motor 2
only. For motor 3, set up a thermal overload relay between the drive and motor 3, so that the sequence trips an external fault (coast to
stop).
• You cannot switch between V/f patterns during run for motor 3. Even when b1-23 = 1 [Selection REV Parameters = Enabled], the
drive will not switch between motors even when the counterweight signal is input.
• If the frequency reference exceeds the maximum output frequency, then it will still be limited by the maximum output frequency set to
each motor. For example, if you set E1-04 = 60 Hz, E3-04 = 50 Hz, d1-04 [Reference 4] = 60 Hz, and d1-04 as the part of multi-step
speed reference, then the frequency reference for motor 1 will be 60 Hz, and 50 Hz for motor 2.
• Refer to the following for the default settings change as the control method.

Table 3.23 Multi-Funciton Digital Input
H1-xx
Setting Value
Name Description
16 Motor 2 Selection Switches between motors 1 and 2.
ON: Selects motor 2
OFF: Selects motor 1
39 Motor 3 Selection Switches to motor 3. It is necessary to set H1-xx = 16 when setting H1-xx = 39. If H1-xx = 39 is
set while H1-xx = 16 is not set, oPE03 [Multi-Function Input Setting Err] is detected.
ON: Selects motor 3
OFF: Clears the selection of motor 3
Note:
When H1-xx = 16 and/or 39, the drive does not detect oPE08 [Parameter Selection Error] concerning contradictory settings in the
MFDIs, MFDOs, analog inputs, and monitor outputs. The drive recognizes terminals that have not been set to a function as "Not Used".
