Hello!

I have one SED2 drive and i need to setup it to simple custom installation. I have loosed plenty of hours trying to reset/setup/configure/tune... drive. Looks like I have missed something...
I have found manual 125-3202 (Rev. 3, August, 2002), and others...

Moreover I have found Micromaster 440 manual with nice and handily Function diagrams, that explains a lot (there is no such diagrams in SED2 manuals)

So the problem is:
I can't get working PID in Auto mode. I have found suitable example (in Micromaster 440 manual), but seems, like SED2 has to be configured different...

PID gives correct output frequency, but drive does not start. I have read status words - there is some kind of start inhibit. Cant figure how to solve this...

So there is my HW configuration:
1) DIN1 - ON signal
2) AIN1 - pressure sensor (4..20mA=0..10bar)
3) while DIN1=24V, motor have to create 2.5bar at the output.

initial setup + reset

P0010	1	Quick comissioning
P0100	0	50Hz (setj)
P0304	380	V(triangle)
P0305	35.8	A (triangle)
P0307	18.5	kW
P0308	0.86	cosPhi
P0310	50	Hz
P0311	2960	rpm
P0640	110	% of P0305
P0700	2	Comand Source
P1000	1	SP source (AI)
P1080	32	Hz min
P1082	50	Hz max
P1120	0.5	s Ramp UP
P1121	10	s Ramp down
P3900	1	end+calc+reset

AIN1 setup

P0003	3	Access level
P0756	2	0-20mA
P0753	300	ms Analog filter
P0757	4	(4mA)
P0758	0	0.00%
P0759	20	(20mA)
P0760	100	100.00%
r0752	???	AV mA
r0754	???	AV %

DIN1 setup+ PID setup

P701(0)	16	DIN1 mode
P2201	25	SP (2.5 bar)
P2253(0)	2224	SP source
P2264(0)	755.0	FB source
P2306	1	Heating mode
P2200(0)	1	PID enable
P2280	0.5	proportional gain
P2285	30	integration time
r2262		Actual SP
r2272		Actual FB
r2294		Actual PID output
r0024		Actual motor frequency

In Auto mode,
r0024 gives 0, while r2294 and r0020 gives max frequency (50 Hz)
