Tacho control
Suitable actual value encoders
- DC tacho generators
- Brushless tachogenerators with evaluation electronics
- Incremental encoder with evaluation electronics
Note:
AC or three-phase current tachos with rectification
are not suitable.
Connection
Tacho line shielded, connect the shield to the device.
Tacho lines must be laid separately from the power lines (EMC).
Control electronics
(adhere to MANUAL REG)
For a positive command value
Positive tacho
X 1:8b
Negative tacho
X 1:9
Shield
X 1:8
Armature voltage control
For 4Q control with a small control range
(up to 1:50) and low demands on accuracy
and dynamics it is possible to use the
armature voltage as actual value signal.
Ground-referenced actual value
Fuses
2 x 0.1A
directly at the tap of the armature voltage
Armature voltage
>180 V
=
additional resistors
Use the (manufacturer) EXZU-UA1 device.
Note: adhere to the MANUAL REG
A potential-free armature voltage control is possible by using the
Unitek unit QTV 2-3.
