6.5 Velocity mode motion

@ Name

_8158_tv_move – Accelerate an axis to a constant velocity with

trapezoidal profile

_8158_sv_move – Accelerate an axis to a constant velocity with

S-curve profile

_8158_emg_stop – Immediately stop

_8158_sd_stop – Decelerate to stop

_8158_get_current_speed – Get current speed

_8158_speed_override – Change speed on the fly

_8158_set_max_override_speed – Set the maximum over-

ride speed

@ Description

_8158_tv_move:

This function is to accelerate an axis to the specified constant

velocity with a trapezoidal profile. The axis will continue to

travel at a constant velocity until the velocity is changed or the

axis is commanded to stop. The direction is determined by the

sign of the velocity parameter.

_8158_sv_move:

This function is to accelerate an axis to the specified constant

velocity with a S-curve profile. The axis will continue to travel at

a constant velocity until the velocity is changed or the axis is

commanded to stop. The direction is determined by the sign of

velocity parameter.

_8158_emg_stop:

This function is used to immediately stop an axis. This function

is also useful when a preset move (both trapezoidal and S-

curve motion), manual move, or home return function is per-

formed.

_8158_sd_stop:

1 2 ... 135 136 137 138 139 140 141 142 143 144 145 ... 219 220
