6.6 Option: Pseudo DC-Motor mode (not supported by
The velocity of the motor in this mode is
changed through a constant voltage at the
General Purpose input. The operational
voltage is 7...48V. This option may be
available in a future firmware version.
6.6.1 Setting up the module
It is advised to connect an external voltage
divider to the GPI pin, as depicted.
However, there are two free places for 0805 SMD resistors to be equipped directly on the module IDX.
To enable this mode solder use resistors as follows:
Attention:
6.6.2 Parameterizing with RS485
First set Parameters for minimum voltage, maximum voltage and a zero point in between. Other
values can be changed also like max. acceleration, max. velocity, microsteps,…
Before enabling this mode with the RS485 command
Purpose Input (GPI). The voltage has to exceed zero point voltage before the regulation works.
6.6.3 Motion Control
Change the voltage at GPI between 7…48V. The motor will accelerate and decelerate relative to the
specified zero point. Additional parameters like resolutions of microsteps can be stored in the
EEPROM.
