Input
Digital input (a24V signals), internal 10k pull-
down resistor
Can be used as:
HOME switch input
GAP 9, 0
// home switch status
STOP_L / STOP_R input
GAP 10, 0
// right limit switch status
GAP 11, 0
// left limit switch status
General purpose digital input 0 (IN0)
GIO 0, 0
// IN0
Table 4.2: Power, RS485 + IN0 connector
Please note:
-
RS485: there is no line termination etc. on-board. Please ensure proper RS485 cabling and line
termination.
-
HOME / digital input IN0: input offers pull-down resistor, input series resistor and protection diodes.
This way input is protected for voltages up-to nom. +24V. The pull-down resistors also ensure a valid
(low) level when left unconnected.
CAUTION
Always keep the power supply voltage (VDD) below the upper limit of 30V!
Otherwise the driver electronics will be seriously damaged. Especially, when the selected operating voltage
is near the upper limit a regulated power supply is highly recommended.
