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.
This requires the index 0x8010:19 [}166] (0x2002:19 [}147], DS402 profile) "Nominal DC Link Voltage" of
the connected voltage to be set accordingly
Setting further parameters
Single-turn Bits (MDP742: Index 0x8000:12 [
}
165] / DS402: Index 0x2010:12
[
}
149]) / Multi-turn Bits (MDP742: Index 0x8000:13 [
}
165] / DS402: Index 0x2010:13
[
}
149])
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.
Note
The motor may overheat!
If the number of single-turn bits is changed, the scaling factor in the NC [}97] has to be
adjusted
Fig.121: Multi-turn / single-turn bits:
Torque limitation (MDP742: Index 0x7010:0B [
}
173] / DS402: Index 0x6072:0 [
}
152])
Limits the current / torque to this value. The value is specified in 1000th of the rated current.
Integral velocity controller component Tn (MDP742: Index 0x8010:14 [
}
166] /
DS402: Index 0x2002:14 [
}
147])
The values specified here are exemplary, although in most cases they have led to excellent results.
Depending on the application, other values may yield better results.
• Reduce the value, until the motor starts to oscillate slightly. Then increase the value by 10%.
