starts running when the power comes back, provided there’s an active RUN
command.
Q How to display the motor speed in rpm?
A To be able to display the speed in rpm, an encoder must be used (and the option card
EME-PG01).
Pr00-04=14 (Press MODE until display shows [G xxx]. (When Pr00-03=3, it shows
the value as selected by Pr00-04 as start-up display). Please set Pr13-00, Pr13-01,
Pr13-02 acc. to the used encoder.
Q Which parameters can be used to save data (RS-485 or PLC)?
A In principle any unused parameter can be used to save data.
In Newsletter 2007-01 it was suggested to use the Preset Speeds (Pr05-00 to 05-14)
for this but these parameters are saved in EEPROM (written) whenever they are
changed. It could lead to exceeding the number of EEPROM write operations and
fault cF1.0 or cF2.0.
Therefore, it is better to use (one of) the following parameters hereafter, they are not
used in their original function.
Pr01-11; Pr01-12; Pr01-13; Pr01-14; Pr02-11; Pr02-12; Pr10-02; Pr10-03; Pr10-04.
They are only saved at power off.
Q Is it possible to use option card EME D33A with NPN inputs and use VFD-E with
PNP inputs?
A Yes, this is possible. Bear in mind that the 24V on the control board is the same as
the 24V on the option card, also DCM on both are the same.
Q Where can a warning be read by serial communication?
A In address 2100hex both warnings and alarms are saved.
The MSB (Most Significant Byte) contains the warning code.
The LSB (Least Significant Byte) contains the alarm code.
Please see examples below:
2100hex = 0D00hex (PTC2 warn code 13)
2100hex = 0022hex (PTC1 fault code 34)
