10.2 LED RSP
RSP is bit when:
—
switch is open, controller release, see 8
-
switch is closed, controller inhibit, see 8
—
excessive temperature of the heatsink
(for 495 and 496)
—
bridge changeover
— phase failure.
When RSP is bit, the firing pulses are in the inverter limit
position.
10.3 LED
1iuax
1 is lit when the speed controller is operating at
i~~~limit.
10.4 LED SEQ
SEQ is lit when the rotating field is incorrect (00W rotation)
and the firing pulses are suppressed.
11. Additional soldering posts
* no standard element
O 107* integral component of the speed controller
O 102, R 101 actual speed value (differential component),
standard wire bridge
R 103 NO ~offs when the 1.Smfl resistor is removed
R 207
R 209
for option board
R 305 quick stop for option boards SWI,
standard 24K3fi
R 309 When actuating the quick stop, the integral
component of the speed controller is inhibited
R 310 Hysteresis of the direotion sensor,
standard 100 fl
R 311 When removing R 311 only fault indication at
terminal 19 without controller inhibit
R 621 Aiaplification for 1 control, standard 39 k~7Z
R 705 Speed controller output for external ‚max
potentiometer
R 719 Adaptation of the current controller,
standard 3K3~l
For fully compensated motors it may be
necessary to inorease the resistance in order
to stabilize the current controller
