3.1.4 Set ting Mo tor Cur rent
Motor current can be set using DIP Switch S1 positions 6, 7, and 8
as shown. Current should be compatible with motor current
ratings.
Note: Power dissipation in the 6410 drive increases as the output
current is increased, so that more cooling is required at high
motor currents.
3.1.5 En able Sense Con trol
The polarity of the enable input can be changed using Jumper J6
position 5-6. With the jumper removed (factory default), the drive
is enabled when the enable input is not driven and disabled when
driven (current flows in enable opto). This allows the 6410 to be
used with no connection to the enable input. With the J6 5-6
jumper installed, the enable input must be driven (current in opto)
for the 6410 power stage to be enabled.
3.1.6 Step Band width Ad just ment
A digital filter can be enabled which reduces susceptibility to
noise on the step input at the expense of a lower limit on
maximum step frequency. With Jumper J6 positions 1-2 installed
(factory default) the filter is enabled and step pulses must have a
minimum width of one microsecond. Pulses less than 0.5
microseconds in width will be rejected. With the filter disabled,
Jumper J6 position 1-2 removed, step pulses must be a minimum
of 0.25 microseconds wide. Therefore, the maximum step
frequency is 500 KHz with the filter enabled and 2 MHz with the
filter disabled.
