Shaft Stationary
This parameter Enables/Disables a continuous DC injection at half of the
amperage setting of the DC Injection Braking Current parameter into a
stopped motor. This feature is useful in preheating the motor or to keep a
stopped motor from spinning freely.
Motor Shaft Stationary Control starts after the DC injection brake stops the
motor and continues until ST-to-CC is opened, power is turned off, receiving an
Emergency Off command, or this parameter is changed.
To use this feature, a non-zero entry at the DC Injection Braking Start
Frequency parameter is required.
