VFD500 high performance vector control frequency inverter user manual Chapter 5 function code table
0: ABZ
1: ABZUVW
2: Rotary/resolver
3: sin/cos encoder
➢ Consult factory when need PG card
1～65535
Rotary pulse number: 1024× rotary pair of poles
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

➢ unit set by P21.17。
➢ no symbolic number，Function code
r27.02:Bit5 for direction；keypad
indicator【REV】indicate direction
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
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。
