If inductive loads (e. g. a relay, motor brake) are connected, a protective diode must be
mounted.

position Basic
Output
This signal is generated when the internal ring counter passes through zero, after the unit
is switched on and after a reset.
Every …. is generated for the step resolution
4th control pulse Full step
8th control pulse Half step
16th control pulse 1/4-step
20th control pulse 1/5- step
40th control pulse 1/10- step
80th. control pulse 1/20- step
The basic position signal can be used in combination with a limit switch to determine the
machine's zero.
position Basic (ZERO SIGNAL) is displayed by the green LED on the MSX front panel.
Basic position is also signaled during switch-on, unless an error message.
Remark:
If the motor is not energized, the position Basic signal is generated anyway.
