Short setup
Step 2: Parameterising the application
5. Enter gearbox ratio as a quotient (numerator and denominator): i
1
= 12.612 = 12612/
1000
– Numerator (C02520) = 12612
– Denominator (C02521) = 1000
6. Set feed constant (C02524).
– The feed constant corresponds to the motion of the machine at one revolution of the
gearbox output shaft.
– For the conveyor drive: Vk = d
1
* π = 628.32 mm
7. Set the selection "mm" as unit (C02525).
– This parameter is used to define the real unit of the machine for the selection of
physical values (e. g. speeds, accelerations and decelerations).
8. If necessary, adapt the setpoint gain (C03002) for analog input 1.
– The setpoint is selected via analog input 1 using the following normalisation:
10 V = 100 % internal setpoint = reference speed of motor (C00011)
– If a lower voltage is available for the setpoint selection, set the setpoint gain as
follows: C03002 = 100 % * 10 V / max. input voltage
9. Select fixed setpoint 1 (C03500/1).
– As an alternative to the analog setpoint, the fixed setpoint can be activated by
setting digital input DI4 to HIGH level.
10. Select the acceleration time (C03502) for accelerating the drive, e.g. "0.5 s".
11. Select the deceleration time (C03503) for decelerating the drive, e.g. "0.5 s".
12. For low-jerk acceleration:
Select "S-shaped ramps" as profile mode for the ramp generator (C03010).
13. When selecting the profile mode "S-shaped ramps", select the S-ramp time (C03504).
Note!
The manual jog function requires the following gearbox ratio and feed constant
settings.
• The manual jog function is parameterised in machine units.
• The selected gearbox ratio and the feed constant are furthermore used to
calculate the reference speed of the machine "online".
