Startup with 87 Hz characteristic curve
Startup
Example:
The following information will be sent to the drive if:
• the binary inputs are configured and wired correctly to enable the drive
• parameter P-12 is set to 3 to operate the drive via SBus
The process data read back from the drive should be in run condition:
5.4 Startup with 87 Hz characteristic curve
The following parameters have to be set:
• P-01: 87 Hz
• P-07: 400 V
• P-08: Motor current for ∆ operation (see nameplate)
• P-09: 87 Hz
Description Value Description
PO1 Control word 0 Fast stop on 2nd deceleration ramp ( P-24 )
1 Coast to stop
2 Ramp to stop on process ramp P-04
3 – 5 Reserved
6 Ramp up ( P-03 ) and run with setpoint speed (PO2)
PO2 Setpoint speed 0x4000 = 16384 = maximum speed, e.g. 50 Hz ( P-01 ) clockwise
0x2000 = 8192 = 50% of maximum speed, e.g. 25 Hz clockwise
0xC000 = –16384 = maximum speed, e.g. 50 Hz (P-01) counterclockwise
0x0000 = 0 = minimum speed as set in P-02
Description Value Description
PI1 Status word 0x0407 Status = run
Output stage enabled
Drive ready
PO data enabled
PI2 Actual speed Should be equal to PO2 (setpoint speed)
PI3 Actual current Depends on speed and load
