3.1.12 Operation of control axes without power circuit module
If no motor is connected to one of the axes, interconnect terminals 13 and 55.1 on
connectors X111 (axes 1 and 4), X 121 (axes 2 and 5), X131 (axes 3 and 6) on the control
module using a 4.7 kohms resistor (see Fig.
3.10).

The pulse cables must be provided with a terminating connector in order to prevent
disturbances during operation without power circuit

3.1.13 Matching the current controller gain
Stability problems may arise in the control circuit when DC servomotors are used which have
a relatively high armature circuit inductance (La> 20 mH,
e.g.
1HU3056-0A(01) or with low
inductance (La
<
2 mH,
e.g.
1HU3078-0AF01). In this case the gain of the current controller
must be increased for motors with high inductance or reduced for motors with low
inductance.
The current gain can be varied by resistors R95 (axes 1 and 4), R98 (axes 2 and 5) and R101
(axes 3 and 6) on the adjustment module (Table
3.13).
The current gain has been adjusted in the works to Kp(l)
=
approx.
2.6
with R95, R98 and
R101 set to 680
ohms.
