Adaptation of current and voltage
Attention
The motor may overheat!
In order to prevent overheating of the connected motor, it is important to adjust the voltage
of the servo terminal to the actually connected voltage.
To this end set the index 0x8010:19 [}137] "Nominal DC Link Voltage" of the connected voltage as required
Setting further parameters
Single-turn Bits (MDP742: Index 0x8000:12 [
}
136] / DS402: Index 0x2010:12 [
}
155]) / Multi-turn Bits
(MDP742: Index 0x8000:13 [
}
136] / DS402: Index 0x2010:13 [
}
155])
Here the user can specify how many single-turn and multi-turn bits the terminal should display. A total of 32
bits are available. These 32 bits can be subdivided as required.
The standard setting is 20 single-turn bits and 12 multi-turn bits.
Singleturn bits: number of bits relating to the resolution of one rotor rotation.
Multiturn bits: after a rotor rotation the multi-turn bits are incremented by one.
Attention
The motor may overheat!
If the number of single-turn bits is changed, the scaling factor in the NC [}110] has to be
adjusted

Automatic gain control
Each resolver has a small difference between the amplitude of the sine and cosine tracks (see Fig. Resolver
gain adjustment). This deviation depends on the variance of the components and other factors and may vary
from motor to motor.
