Multiple Motor Control (MMC) Basic Sequence
Multiple motor control (MMC) is an operation based on PID control. During an MMC operation,
the main and auxiliary motors organically operate together.
During a PID operation, the auxiliary motors are turned on when the inverter frequency reaches
the start frequencies set at AP1-61–65 (Start freq), and the difference between the PID reference
and feedback is bigger than the value set at AP1-50. Then, the auxiliary motors stop operating
when the operation frequency reach the stop frequency set at AP1-70–74 (Stop Freq 1–5) and the
difference between the PID feedback and reference becomes greater than the value set at AP1-50.
AP1-51 Acc Time
AP1-52 Dec Time
Parameters used when AP1-40 is set to ‘Single Ctrl’
When an auxiliary motor starts or stops, the main motor stops the
PID control, and performs general acceleration and deceleration.
When an auxiliary motor starts, the main motor decelerates to the
auxiliary motor deceleration frequency set at AP1-70–74 (Stop Freq
1–5) based on the deceleration time set at AP1-52 (Dec Time).
When the auxiliary motor stops, the main motor accelerates up to
the auxiliary motor restart frequency set at AP1-61–65 (Start Freq 1–
5) based on the acceleration time set at AP1-51 (Acc Time).
AP1-53 Aux Start DT
AP1-54 Aux Stop DT
The auxiliary motors turns on or off after the auxiliary motor stop
delay time or the auxiliary motor restart delay time elapses, or if the
difference between the current reference and the feedback is greater
than the value set at AP1-50 (Actual Pr Diff).
AP1-61–65 Start Freq1–5
Sets the auxiliary motor start frequency.
AP1-70–74 Stop Freq 1–5
Sets the auxiliary motor stop frequency.
AP1-95 AuxRunTime Sel
Selects auxiliary motor to be used in AP1-96 and AP1-97.
AP1-96 AuxRunTime Day
Indicates operating time(day) selected in AP1-95.
AP1-97 AuxRunTime Min
Indicates operating time of auxiliary motors selected in AP1-95.
AP1-98 AuxRunTime Clr
Deletes operating time of auxiliary motors.
OUT-31–35 Relay 1–5
OUT-36 Q1 Define
Configure the output terminals to ’21 (MMC)’ to use the terminals to
control the auxiliary motors. The number of the configured output
terminals determines the total number of auxiliary motors to be
used.
