Sleep Operation
APP-66: Auto Change Mode Selection
This function is used to change the running order of
the motors to regulate and balance their run-times
when multiple motors are connected for MMC use.
EXCH_NONE Mode:
Auto Change Function
Disabled.
The drive is controlling a main motor (permanently
connected to output of drive) and activating relays
(AUX1~AUX4) to connect Auxiliary motors in a
fixed order. For example, starting from the Aux
motor 1 (APP-41 = 1), the drive turns the relays ON
from
RLY1
→
RLY2
→
RLY3
→
RLY4
and turns off
the auxiliary motors from
RLY4
→
RLY3
→
RLY2
→
RLY1
.
AUX_EXCH Mode:
Auto Change Function is
applied only to aux. motors. Starting of Auxiliary
motors is automatically rotated by the drive in
AUX_EXCH Mode to prevent a specific motor from
operating more than the other motors. On/Off
sequence of auxiliary motors is fixed using
EXCH_NONE Mode
but rotates the sequence
(alternates) using AUX_EXCH Mode. For example,
when Aux motors running order is presently
RLY1
→
RLY2
→
RLY3
→
RLY4
and the Auto
change condition is met, the drive would then turn the
relays On from
RLY 2
→
RLY3
→
RLY4
→
RLY1
.

EXCH_NONE and AUX_EXCH
Modes are for
use when a Main motor is permanently connected to
the output of the drive.
MAIN_EXCH Mode:
Auto Change of motors to
drive output.
All motors are alternately connected to the drive
output via relays/contactors. The sequence operation
is the same as AUX_EXCH Mode, except that there
is no main motor permanently connected to output of
drive. See Interlock diagram.
APP-67: Auto Change Time
APP-68: Auto Change Level
The Auto Change function is used to prevent one
motor from running for a long time by changing
operation to another motor.
