Forced cooled systems, NY4140
The NYCe 4000 system can be installed with a standard fan unit with 3 fans
each producing an airflow of 11.3 m
3
/hr. When five NY4140 drive modules
are used in the NY4053 system housing, you can build the maximum
configuration with 5 axes.
fig. 17-9 "Max. motor current for 5 axes (5 NY4140
drive modules, PWM frequency = 32 kHz) and all digital outputs at 1 A load
/hr) installed vs. environmental temperature" on
shows the situation where all 5 motors ask continuously the same
motor current, PWM frequency is 32 kHz, and all 10 digital outputs drive a
load of 1 A continuously. Under these conditions the maximum motor current
is 7 A rms at an environmental temperature of up to 55 °C.
