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.

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".
