Set up phase currents correctly fitting to the motor winding's design current!
•
The stop current is normally set to 40-50% of the run current, to keep the motor
temperature as low as possible.
•
The table values refer to current values, if both motor phases are activated. The
current in one phase is calculated as: table value x
2
•
Max. run /stop current in Rotary switch mode: range
I
: 1.6 A x
2
x 1.3 = 3 A
range II : 5 A x
2
x 1.3 = 9 A
•
Important: The run and stop current values, which are set by the rotary switches,
depend on the selected current rage, that means
Run current
(without Boost) Stop current
(without Boost)
Range
I
0.2 to 1.6 A

0.2 to 1.6 A

Range II 0.6 to 5 A

0.6 to 5 A
r.m.s.
The switch positions may be changed
•
while the MCD is powered off or
•
the power stage is deactivated. However, after changing the switch
position the power stage should be reset by the input Reset.
Short circuit phase to phase and phase to ground is detected from a current
setting of 0.7 A
r.m.s.
