Valid for S300, S700
Table of Contents
The S300 / S700 servo amplifiers are a great solution for most High Frequency Spindle applications.
Advantages
- Asynchronous and synchronous spindles
- With or without feedback, please see the frequency limit for feedback on user manual (S300 / S700), for example (Sin, Cos) feedback limited of 350 kHz.
- Simple Tuning / Setup
- Support of many fieldbus systems
- Simple system integration
Guidelines
Maximum adjustable speed in the firmware: VMAX=15,000 rpm
Speed higher than 15,000 rpm can be reached by using virtual pole number setting (speed factor 2 or 4):
- Motor pole number ( MPOLES )
set motor pole number = real motor pole number * speed factor - Feedback (Encoder: ENCLINES , Resolver: MRESPOLES )
set lines/pole number = real lines (pole number) * speed factor
The speed factor must be used for motor speed, motor pole number and feedback pole number.
Possible speed / frequency
| Maximum Output Frequency | Real Motor Pole Number | ||||||
|---|---|---|---|---|---|---|---|
| 599 Hz (see Dual Use) | 2 | 4 | 6 | 8 | 10 | 12 | ... |
| Maximum Speed (RPM) (VMAX * speed factor) | |||||||
| 60,000 | 30,000 | 20,000 | 15,000 | 12,000 | 10,000 | ||
Example
Real situation
- Motor with 2 poles
- Feedback Encoder with 2048 Lines
- Desired speed 25,000 rpm => speed factor= 2 (VMAX * 2 = 30,000 rpm)
Setting
Result
A speed set point of 10,000 rpm causes the motor to turn with 20.000 rpm (speed set point * speed factor).
