Adaptation of current and voltage
The motor may overheat!
In order to prevent overheating of the connected motor, it is important to adjust the voltage of the servo ter-
minal to the actually connected voltage.
This requires the index 0x8010:19 [} 190] (0x2002:19 [} 212], DS402 profile) "Nominal DC Link Voltage" of
the connected voltage to be set accordingly
Setting further parameters
Single-turn Bits (MDP742: Index 0x8000:12 [} 188] / DS402: Index 0x2010:12 [} 216]) / Multi-turn Bits
(MDP742: Index 0x8000:13 [} 188] / DS402: Index 0x2010:13 [} 216])
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.
The motor may overheat!
If the number of single-turn bits is changed, the scaling factor in the NC has to be adjusted
Fig. 158: Multi-turn / single-turn bits:
Torque limitation (MDP742: Index 0x7010:0B [} 198] / DS402: Index 0x6072:0 [} 220])
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 [} 190] / DS402: Index
0x2002:14 [} 212])
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%.
Proportional velocity controller component Kp (MDP742: Index 0x8010:15 [} 190] / DS402: Index
0x2002:15 [} 212])
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.
