13.1. Processing Speed/Torque References
The “main reference” is the value, at constant rpm, for the controlled physical variable (speed or torque) (M000, M007)
“required” for the drive.
This reference is acquired by the drive only if the START command is active and the drive is RUNNING, otherwise it is
ignored.
The main reference is the reference at constant rpm: when the drive is RUNNING, it will increment the speed or torque
set–point which will reach the main reference with a timed ramp (see the RAMPS MENU
).
The drive operating mode is factory-set to MASTER with a speed reference. In SLAVE mode, a torque reference is
used; this operating mode may be configured for VTC control (Vector Torque Control) and FOC control (Field Oriented
Control) only.
The control algorithm and the MASTER/SLAVE mode can be set for each of the 3 programmable motors, depending
on which motor is active at that moment (motor 1, motor 2 or motor 3).
To enable the SLAVE mode, set the following parameters to 1 or 2:
C011 (motor 1)
C054 (motor 2)
C097 (motor 3)
The SLAVE mode may also be selected through a digital input (see the DIGITAL INPUTS MENU).
When the main reference is acquired by the drive (RUNNING on), it becomes the reference for the time ramps
generating the current speed/torque set–point for the connected motor.
The setup of the main reference is based on a number of parameters included in several menus:
