3.5.5.8Motor potentiometer (MOP)

P1031 =...

P1032 =...

P1040 =...

Setpoint memory of the MOP 0

Saves last motor potentiometer setpoint (MOP) that was active before OFF command or power down.

0 MOP setpoint will not be stored

1 MOP setpoint will be stored (P1040 is updated)

Inhibit negative MOP setpoints		1
0	Neg. MOP setpoint is allowed
1	Neg. MOP setpoint inhibited
Setpoint of the MOP		5.00 Hz
Determines setpoint for motor potentiometer control.

MOP ramp-up and ramp-down times are defined by the parameters P1120 and P1121.

Possible parameter settings for the selection of MOP:
	Selection	MOP up	MOP down
DIN	P0719 = 0, P0700 = 2, P1000 = 1	P0702 = 13	P0703 = 14
	or	(DIN2)	(DIN3)
	P0719 = 1, P0700 = 2
BOP	P0719 = 0, P0700 = 1, P1000 = 1	UP button	DOWN button
	or
	P0719 = 11
USS on	P0719 = 0, P0700 = 4, P1000 = 1	USS control word	USS control word
	or
BOP link		r2032 Bit13	r2032 Bit14
	P0719 = 41
USS on	P0719 = 0, P0700 = 5, P1000 = 1	USS control word	USS control word
COM link	or	r2036 Bit13	r2036 Bit14
	P0719 = 51
CB	P0719 = 0, P0700 = 6, P1000 = 1	CB control word	CB control word
	or

Fixed frequency 1	0.00 Hz	When defining the function of the digital inputs
Can be directly selected via DIN1		(P0701 to P0703), three different types can be
(P0701 = 15 16)		selected for fixed frequencies:
		15 = Direct selection (binary-coded)
Fixed frequency 2	5.00 Hz
Can be directly selected via DIN2		In this particular mode, the appropriate
		digital input always selects the associated
(P0702 = 15, 16)
		fixed frequency, e.g.:
Fixed frequency 3	10.00 Hz	Digital input 3 = selects fixed frequency 3.
Can be directly selected via DIN3		If several inputs are simultaneously active,
(P0703 = 15, 16)		then these are summed. An ON command is
		additionally required.
Fixed frequency 4	15.00 Hz
		16 = Direct selection + ON command
		(binary-coded + On / Off1)
Fixed frequency 5	20.00 Hz	In this mode, the fixed frequencies are
		selected as for 15, however these are
Fixed frequency 6	25.00 Hz	combined with an ON command.
		17 = Binary coded selection + ON command
		(BCD-coded + On/ Off1)
Fixed frequency 7	30.00 Hz
		The BCD-coded operating mode is effective
		for digital inputs 1 to 3.
