[*2]. Safety Circuit Inputs
Inputs X203 - X210 primarily function are the same as the other normal inputs.
However, there is the option to use these inputs as part of the safety circuit by
soldering a bridge across one or more pairs of the solder pads, which are shown in
the image below. The i203 bridge is already soldered by default.

[*3]. CP override
This allows the user disable charge pump function. Soldering solder-bridge makes CP
signal always on

[*4]. Off Delay timer
This feature can be used where an “OFF DELAY” is required, such as in “Z-Drop”
protection, which allows a mechanical brake to engage before the motor loses its
holding torque. This can happen after the control signal or the main power is cut
from its drive. Solder the bridge at K1 to enable an off delay of 440 ms, or at K2 for
660 ms.
