Q Which brake resistors to use for VFD-E ?
A The brake resistors are given in the VFD-E manual (Chapter B1) but not all types are
specified or stated. You can either buy it locally or "build" them from several individual
brake resistors. Please also refer to the Datasheet Brake Res Version8 Mar2019.pdf
on the ftp-site (Industrial Automation Products\AMD-Options\AMD Brake units &
resistors\Brake resistors for available types). Remember the total resistance must
never be lower than the indicated minimum and the power maybe higher.
Q How to make AVI=0-10V=Fmax-0 (reversed)?
A In 1.15/2.15 and higher it is possible in a normal way.
Pr04-11=0, Pr04-12=100%, Pr04-13=10, Pr04-14=0.
Q Which parameters are only saved in EEPROM at power-off and not when
changed?
A The following parameters are only saved in EEPROM at power off and can be used
in a PLC program to avoid frequent writing by serial communication or WPR
instruction:
Pr01-09 1st Acc time
Pr01-10 1st Dec time
Pr01-11 2nd Acc time
Pr01-12 2nd Dec time
Pr01-13 JOG Acc time
Pr01-14 JOG Dec time
Pr01-17 S-Curve Acc time
Pr01-18 S-Curve Dec time
Pr10-02 P value of PID function
Pr10-03 I value of PID function
Pr10-04 D value of PID function
Pr10-12 PID set point
Besides, VFD-E offers two parameters, P09-05 and P09-06, for temporary buffer.
Users can use WPR to write to these parameters. However, these parameters will not
be written to EEPROM when power off.
