Safety and assembly rules
1.1
Safety rules
Prior to first start-up of the device carefully read the manual.
Prior to first start-up of the device make sure all cables are properly connected.
Provide appropriate working conditions, in compliance with the device
specifications (e.g.: power supply voltage, temperature, maximum current
consumption).
Prior to any modifications of cables connections, disconnect power supply voltage.
Driver can achieve high temperatures at longer operation and full load; hot housing can
cause burn!
1.2
Assembly recommendation
It is recommended to use the following means preventing against possible interruptions of the device
operation:
1.
To
minimize noises
, cable which connect motor with driver should be shielded or twisted in
pairs (separate twisted pair for A and B phase). It is also recommended to use a
ferrite ring
on motor cable at controller.
2.
Signal cables
(CLK, DIR, EN) should
be move away from power supply line and motor wires
and should be possibly short.
3.
Setting
too high current
for weaker motor cause its asynchronous operation, especially at set
higher step division (motor coils saturation). In longer period of time it cause stronger
heating of the motor, and in consequence it leads to its damage.
4.
At operations with high currents please provide its proper cooling. It is recommended to not
Mount the driver in control cabinet without additional air circulation.
CAUTION!
During driver operation with higher currents (>3A) it can achieve higher temperatures.
To provide its proper operation please provide proper cooling by forced air circulation. Driver
operations in closed control cabinet without forced air circulation can cause its overheating and
turning off.
