8.2 MIS23x Registers
8.2.12 V_START
Description: The start velocity. The motor will start the acceleration at this velocity. It will also stop
the deceleration at this velocity. If |V_SOLL| is lower that V_START the motor will not
accelerate at all, but start to run at V_SOLL instantly. The motor will actually start the
movement with an internal V_START = V_SOLL.
If V_START is changed during a movement, it will first be active when the motor stops
or changes direction. This also means that if V_SOLL is changed to a value below
V_START, while the motor is in motion, the motor will decelerate to V_START
and run at that velocity.
Example: V_START = 100, V_SOLL = 200, MODE_REG = 1. The motor will accelerate from 100
RPM to 200 RPM.
V_SOLL is now changed to 50. The motor will decelerate to 100 RPM and continue
at 100 RPM.
V_SOLL is now changed to -50 RPM. The motor will stop and start at -50 RPM.
8.2.13 GEAR1
Description: When the gear mode is active, the input from the external encoder is multiplied by
GEAR1 and divided by GEAR2.
Example: GEAR1 = 1600, GEAR2 = 2000. If 2000 steps are applied to the input, the motor will
turn 1 revolution.
If one step is applied, the motor will not move (but the remainder will be 0.8)
If another step is applied, the motor will move 1 step (and the remainder will be 0.6).
If another step is applied, the motor will move 1 step (and the remainder will be 0.4)
And so on.
8.2.14 GEAR2
Description: The denominator of the gear factor. See GEAR1 for details.
8.2.15 Encoder_Pos
Description: If the internal encoder option is installed, this register shows the position feedback from
the encoder. This value is initialized to zero at power-up and modified by the firmware
when a zero search is performed. The value can be used internally by the AutoCorrec-
tion system to retry a movement in position and gear modes.
