Open Loop Modality

Open loop modality is working if the Drive_Working_Settings.Motor Feedback_Check bit = 0.

This is the traditional use of a stepper motor. For open loop modality, use a stepper motor without an encoder.

Below is the list of Objects necessary for the configuration of the drive to work in open loop.

Object Name	Note
Motor_Pole_Pairs	Mandatory
Motor_Step_Angle	Mandatory
Min_Current	Mandatory
Max_Current	Mandatory
Nominal_Current	Mandatory
Min_Profile_Velocity	Mandatory
Max_Profile_Velocity	Mandatory
Profile_Velocity	Mandatory
Motor_R	Typically set to the motor catalog data for Resistance (Motor_R) and Inductance (Motor_L). If Resistance is in Ohms and Inductance is in mH, then multiply values by 1000 when entering values into this parameter. Alternatively, omit the values if Motor RL Detection is enabled in the Working Setting tab in the Global Parameters window. (Drive_Working_Settings.Motor_RL_Detection bit = 1).
Motor_L
Motor_Start_Delay	Optional, typically set to 0. Defines a delayed start based on a set amount of time. If set to 50,000, this means 50,000 micro-seconds. The motor will start after a 0.5 second delay.
Motor_Start_Delay_Pulses	Optional, typically set to 0. Defines a delayed start based on input pulses. Ex. If set to 5, the motor will start on the 6^th pulse input.
Drive_Working_Settings	This Object allows the user to set some working features.
Drive_Working_Settings_Extended	This Object allows the user to set some working features.
