Setting the motor parameters

Procedure:

1. Open the "CoE - Online" tab.
2. Set all parameters described below.
Leave all parameters not described in the factory setting.

The values for the parameters can be found in the motor data sheet.

Setting the motor parameters 1:

8020:01 "Peak current"

Unit: mA

The peak current, which may only flow for a short time.

8020:02 "Rated current"

Unit: mA

The rated current is the current that the motor draws when it is operated at the rated speed and rated torque.

8020:03 "Rated voltage"

Unit: 0.01 V

8020:04 "Phase to phase resistance"

Unit: 0.01 Ω

DC resistance, measured between two motor phases.

Note: from firmware 04, this value is determined automatically when scanning the motor. See next chapter Scan motor (only firmware 04 and higher).

8020:09 "Start velocity"

Unit: °/s (degrees per second)

There are two ways to calculate the value for this parameter:

 

Setting the motor parameters 2:

nstart: Value for parameter 8020:09 "Start velocity"

i: Transmission ratio.
   (i = 1 if no gear unit is used)

v: Nominal velocity in m/s
    (Note: v [m/s] = v [fpm] / 196.85)

d: Conveyor roller diameter in m

 

Setting the motor parameters 3:

nstart: Value for parameter 8020:09 "Start velocity"

nN: Nominal velocity of the motor in rpm

i: Transmission ratio
   (i = 1 if no gear unit is used)

8020:13 “Mechanical to electrical ratio”

You can calculate or experimentally determine the value for this parameter.

 

Setting the motor parameters 4:

r: „Mechanical to electrical ratio”.

p: Number of pole pairs of the motor.

i: Transmission ratio.
   (i = 1 if no gear unit is used)

1) Calculation example with number of pole pairs = 4 and transmission ratio = 12:1:
   "Mechanical to electrical ratio" = 4 x 12 = 48.

8020:14 “Rated velocity”

Unit: °/s

Nominal speed of the conveyor roller.

8020:19 “Motor thermal time constant”

Unit: 1/10 s (1/10 of a second)
