9001
203C / 2
ACC
R/W
Acceleration ramp time
Unit: 0.1 s
Factory setting: 30
Adjustment range: According to parameter Inr
Defined for accelerating between 0 and the nominal frequency FrS (page
).
9002
203C / 3
dEC
R/W
Deceleration ramp time
Unit: 0.1 s
Factory setting: 30
Adjustment range: According to parameter Inr
Defined for decelerating between the nominal frequency FrS (page
) and 0.
Check that the value of dEC is not too low in relation to the load to be stopped.
9010
203C / B
rPS
R/WS
Ramp switching
Factory setting: 0
This function remains active regardless of the control channel.
0 = "nO": Not assigned
129 = "LI1": Logic input LI1
130 = "LI2": Logic input LI2
131 = "LI3": Logic input LI3
132 = "LI4": Logic input LI4
133 = "LI5": Logic input LI5
134 = "LI6": Logic input LI6
If LAC = L3, the following assignments are possible:
171 = "Cd11": bit 11 of the CMD control word (page
) written by Modbus or CANopen
172 = "Cd12": bit 12 of the CMD control word (page
) written by Modbus or CANopen
173 = "Cd13": bit 13 of the CMD control word (page
) written by Modbus or CANopen
174 = "Cd14": bit 14 of the CMD control word (page
) written by Modbus or CANopen
175 = "Cd15": bit 15 of the CMD control word (page
) written by Modbus or CANopen
ACC and dEC are enabled when the logic input or control word bit is at state 0.
AC2 and dE2 are enabled when the logic input or control word bit is at state 1.
9011
203C / C
Frt
R/WS
Ramp switching threshold
Unit: 0.1 Hz
Factory setting: 0
Adjustment range: 0 to 5000
The second ramp is switched if the value of Frt is not equal to 0 (0 deactivates the function) and
the output frequency is greater than Frt.
Threshold ramp switching can be combined with switching via LI or bit as follows:
9012
203C / D
AC2
R/W
2
nd
acceleration ramp time
Unit: 0.1 s
Factory setting: 50
Adjustment range: According to parameter Inr
Enabled via logic input (rPS) or frequency threshold (Frt).
9013
203C / E
dE2
R/W
2
nd
deceleration ramp time
Unit: 0.1 s
Factory setting: 50
Adjustment range: According to parameter Inr
Enabled via logic input (rPS) or frequency threshold (Frt).
9003
203C / 4
brA
R/WS
Deceleration ramp adaptation
Factory setting: 1
Activating this function automatically adapts the deceleration ramp, if this has been set at too
low a value for the inertia of the load.
0 = "nO": Function inactive
1 = "YES": Function active. The function is incompatible with applications requiring:
- positioning on a ramp
- the use of a braking resistor (the function may not operating correctly)
brA is forced to nO if brake control bLC is assigned (page
).
