Servo controller ECS
The input and output variables of the speed controller are normalised to the maximum
current I
max.
(C0022) and the maximum speed n
max
(C0011). This allows C0022 and C0011
to directly influence the gain of the speed controller Vpn.
ƒ The following applies to the servo controller ECS:
– Vpn proportional n
max.
(C0011)
– Vpn proportional 1/I
max.
(C0022)
Parameter setting of motor temperature detection
Stop!
ƒ The integrated overload protection does not prevent overload under
all conditions!
ƒ Reduce maximum current to required value!
The motor winding temperature is monitored by thermal detectors.
Function block interconnection
Stop!
Perform function block interconnection (servo inverter 9300) or I 2 xt
monitoring (servo inverter ECS) with disconnection after several seconds of
operation with I > I
N
, particularly in case of danger of blocking.
