8.3 MIS34x & MIS43x Registers
Gear mode (3)
The GEAR mode works as position mode, but has an additional feature. The input on the
external encoder is multiplied with GEAR1/GEAR2 and added to P_SOLL. Any remain
-
der of the result is saved and used next time the external encoder changes.
The result is that this mode can be used as an electronic gear.
When using gear mode, it is not recommend to set V_START below 10 rpm. This can
gives problems at low speeds, because the motor will lag behind when doing the first
step. It will then accelerate in order to catch up.
NOTE: Time from the first input pulse to the first step is typically 30-60µs if not on
standby. 72-102µs if on standby.
Zero search type 1 (13)
When the operation mode is set to 13, the controller will start the search for the zero
point. See
“Sensor type 1” Zero search, page 110 for details.
Zero search type 2 (14)
When the operation mode is set to 15, the controller will start the search for the zero
point. See
“Sensor type 2” Zero search, page 110 for details.
Safe mode (15)
This mode is similar to passive mode, but also allows the “save in flash” and “reset” com-
mands. Safe mode cannot be entered/exited directly; this must be done using the serial
commands ENTER/EXIT SAFEMODE.
Example:
Writing MODE_REG=2 will set the motor in position mode. When P_SOLL is changed,
the motor will move to this position with the specified max velocity (V_SOLL) and accel
-
eration (A_SOLL).
Writing MODE_REG=13 will start a zero search for a sensor. When the search is com-
pleted, the MODE_REG will automatically be changed to the mode specified in
START_MODE.
8.3.4 P_SOLL
Description: The desired position. When in position mode, the motor will move to this position. This
value can be changed at any time. The maximum possible position difference is 231-1. If
relative movement is used, the P_SOLL will just wrap at 231-1 and the motor will move
correctly. Please note that the turntable function changes the behaviour of P_SOLL. See
Turntable_Mode, page 141.
Example: If P_SOLL = -800 and then P_SOLL is set to 800, the motor moves one revolution
forward.
If P_IST = 231-100 (2147483548) and P_SOLL is set to -231+100 (2147483548), the
motor will move 200 steps in the positive direction.
