8.3 MIS34x & MIS43x Registers
8.3.5 V_SOLL
Description: The maximum velocity allowed. When in velocity mode, the motor will run constantly at
this velocity. Specify a negative velocity to invert the direction. This value can be changed
at any time.
Example: V_SOLL = 25000, will limit the velocity to 250 RPM.
8.3.6 A_SOLL
Description: The acceleration/deceleration ramp to use. If this value is changed during at movement,
it will first be active when the motor stops or changes direction.
Example: A_SOLL = 100, will set the acceleration to 100 RPM/s.
8.3.7 Run_Current
Description: This register sets the running current for the motor. 511 is the maximum possible cur-
rent, corresponding to 3A RMS. The running current is active when the motor is running
and after it stops until the specified standby time has elapsed.
See Standby_Time, page 124.
When the RUN_CURRENT is changed, the new motor current will be set instantly.
Example: RUN_CURRENT = 100, will set the running current to 0.59A RMS.
8.3.8 Standby_Time
Description: This register sets the standby time. This time is the time from the last step has been
performed until the current changes from running to standby. When a new request for
a move is received the current changes from standby to running with no delay.
Example: STANDBY_TIME = 200, will result in the controller switching to the standby current
after 200ms.
