[EthercatDevice_DmpStepper_Generic]
Description
Configure the maximum velocity of the specified machine axis on the EtherCAT slave device in G-code Controller mode. The purpose of this parameter is primarily to limit maximum speed of the motor to prevent exceeding the motor’s specifications. This parameter is written to the EEPROM of the EtherCAT slave device and loaded during startup, so users do not need to configure this parameter each time before running the program.
Derived Class:
| Class Name | Vendor ID | Product Code |
| EthercatDevice_QECR11MP3S | 0x00000bc3 | 0x0086d0d6 |
| EthercatDevice_QECR00MP3S | 0x00000bc3 | 0x0086d0d9 |
Syntax
int configMachineMaxVelocity(int machine_axis, double mm_per_sec);
Parameters
[in] int machine_axis
The specified machine axis number on the EtherCAT slave device:
| Definition | Value | Description |
| ECAT_MACHINE_X_AXIS | 0 | X-axis, which mapping is determined by the configMachineAxisMapping(). |
| ECAT_MACHINE_Y_AXIS | 1 | Y-axis, which mapping is determined by the configMachineAxisMapping(). |
| ECAT_MACHINE_Z_AXIS | 2 | Z-axis, which mapping is determined by the configMachineAxisMapping(). |
[in] double mm_per_sec
The maximum velocity to be configured is in millimeters per second.
Return Value
Return an error code. If the returned value is zero, it indicates a successful execution of this function.
Comment
This function must be called after a successful execution of EthercatMaster::begin(). This function is blocking and cannot be called within the Cyclic Callback.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR11MP3S slave;
void setup() {
master.begin();
slave.attach(0, master);
slave.configMachineMaxVelocity(ECAT_MACHINE_X_AXIS, 300);
slave.configMachineMaxVelocity(ECAT_MACHINE_Y_AXIS, 300);
slave.configMachineMaxVelocity(ECAT_MACHINE_Z_AXIS, 300);
// ...
}
void loop() {
// ...
