6.2.2.5 Quick start-up of an asynchronous motor
The start-up should always be done with co01 modes of operation = 2 "velocity
mode“, also if another operating mode shall be used later.
Drive must not be in operation
co00 (CiA 0x6040) controlword = 0 or hardware modulation lock
Load default data
Default data are automatically loaded in all parameters with co08 = 2 and then
co09 = 1.
Select operating mode
The operating mode is selected in cs00 bit 0…3 (0 = v/f characteristic operation / 1
= with encoder, without model / 2 = with encoder, with model /3 = without encoder,
with model = ASCL)
Preset motor data
With the input of the first motor data the state of dr02 changes to 0 "fill motordata“.
Only the following data are required for v/f characteristic operation:
rated motor current
(for the electronic motor protection func-
tion)
dr04 rated speed / dr06 rated fre-
quency:
dr04 rated speed / dr05 rated voltage:
Rated point
(voltage for rated speed)
Voltage for frequency = 0Hz
dr33 motor temp sensor type:
Selection motor sensor (PTC or KTY)
If no motor temperature sensor is availa-
ble,
the monitoring must be deactivated with
pn12 = 7.
The following data are additionally required for closed-loop operation with or with-
out encoder:
dr32 inertia motor (kg*cm^2)
for automatic parameterization of the
speed controller (together with cs17 inertia
load).
Determination of the magnetizing current
(if it is not known, the default value of dr07
can be used).
