Parameter
Description
p1030
MOP configuration
(factory setting: 00110 bin)
Parameter value with five independently adjustable bits 00 … 04
Bit 00:
Save setpoint after switching off motor
0: After the motor is switched on, p1040 is specified as the setpoint
1: Setpoint is saved after the motor is switched off and set to the saved value once it
is switched on
Bit 01:
Configure ramp-function generator in automatic mode (1-signal via BI: p1041)
0: Without ramp-function generator in the automatic mode (ramp-up/ramp-down time
= 0)
1: With ramp-function generator in the automatic mode
In manual mode (0-signal via BI: p1041) the ramp-function generator is always active
Bit 02:
Configure initial rounding
0: Without initial rounding
1: With initial rounding. Using the initial rounding function it is possible to enter very
small setpoint changes
Bit 03:
Store setpoint in power-independent manner
0: No power-independent saving
1: Setpoint is saved in the event of a power failure (bit 00 = 1)
Bit 04:
Ramp-function generator always active
0: Setpoint is only calculated with enabled pulses
1: The setpoint is calculated independent of the pulse enable.
p1037
MOP maximum speed
(factory setting: 0 rpm)
Automatically pre-assigned when commissioning
p1038
MOP minimum speed
(factory setting: 0 rpm)
Automatically pre-assigned when commissioning
p1043
Motorized potentiometer, accept setting value
(factory setting: 0)
Signal source for accepting the setting value. The motorized potentiometer accepts
the setting value p1044 on signal change p1043 = 0 → 1.
p1044
MOP setting value
(factory setting: 0)
Signal source for the setting value.
