Danfoss VFD500 Series - Group Encoder Type

VFD500 high performance vector control frequency inverter user manual Chapter 5 function code table
10 Group encoder type
P10.01
Encoder type
0: ABZ
1: ABZUVW
2: Rotary/resolver
3: sin/cos encoder
➢ Consult factory when need PG card
0
★
P10.02
Encoder line number
1～65535
Rotary pulse number: 1024× rotary pair of poles
1024
★
P10.03
AB pulse direction
0: forward， 1: reverse
➢ If control mode is VC (with PG card)we can
get this value by auto tuning for motor
➢ We can run motor with open loop,and
observe r10.12 and r27.00 if they are in the
same direction,if not,then change this value
0

r10.12
encoder feedback rotating
speed
Current rotating speed by measuing, unit:
0.01Hz/1Rpm
➢ unit set by P21.17。
➢ no symbolic number，Function code
r27.02:Bit5 for direction；keypad
indicator【REV】indicate direction

●
r10.13
Encoder current position
0 ～ 4*encoder pulse number -1
encoder current position refer Z pulse as zero
point,motor forward running and one cyle to Z
pulse ,then postion to zero
-
●
r10.14
Z pulse marking value
0 ～ 4*encoder pulse number-1
(it is used to monitor encoder slipping and AB
being disturbed )
-
●
When encoder is not installed on the motor rotor axis,asynchronous motor vector control with encoder is
effective by setting motor and encoder rotating speed ratio (P10.07 and P10.08)
For example：if motor rotating speed is 1500RPM and encoder speed 1000RPM，set P10.07=1500，
P10.08=1000。
