this manual.
20 Local / Remote Mode
Value:
0 - 3 0 ([LOCAL/REMOTE] button enabled)
0 = [Local/Remote] push button on MCD3000
enabled all the time.
1 = [Local/Remote] push button on MCD3000
enabled only while motor stopped.
2 = Local control only. (MCD3000 push buttons
enabled, remote inputs disabled)
3 = Remote control only. (MCD3000 push buttons
disabled, remote inputs enabled)
Function:
Determines when MCD3000 push buttons and remote
control inputs are operative. Also when, and if, the
[Local/Remote] push button can be used to switch
between local and remote control.
Description of choice:
Set according to desired operational requirements.
21 Current Gain
Value:
85% - 115%
Function:
Adds a gain to the MCD3000 current monitoring
circuits. These circuits are factory calibrated with an
accuracy of ±5%. The gain can be used to match the
MCD3000 current read out with an external current
monitoring system.
ATTENTION
This adjustment affects all current based
functions. e.g. current read-out, motor
overload & all other current based protections and
current outputs.
Description of choice:
The gain should be adjusted according to the following
formula.
= factory setting
