operation
* Manual operation is a combination of digital input 12 being high and either digital input 10 or 11
being activated.

6.2 Internal flags

The IMD uses some internal flags that are visible as status flags. The same flag may also be mapped
to a register in order to be able to read directly, without need to mask the result (the register value is
either zero or one).

(section 13.2.11 on page 209) and Reg. 0x40 (section

Description
The IMD determines whether to reconnect
mains for the safety run
The motor is controlled by
digital input 10 ("-" direction) and
digital input 11 ("+" direction).
Description
Indicates the state of the Safety-chain relays. 0 = relays tripped, 1 =
relays are ON. This parameter also indicates whether the IMD can
be enabled or not. When the relays are tripped, the IMD cannot be
enabled without clearing the errors and cycling the safety-chain
inputs.
Dev.Enabled is turned on when both "Enable dev." and RUN are
active.
Go is turned on when the IGBT is enabled. In normal circumstances,
it will be turned on together with Dev.Enabled is turned on (when
both "Enable dev." and RUN are active). However, if for some reason
the IGBT is not enabled, it will remain off.
State of the connection between 400VAC to the DC-link.
1: DC-link is disconnected
0: DC-link is connected
Note: this flag is used in the IMD Manager to show the power source
of the DC-link.
The brake output is active.
The brake is in the process of either being activated or deactivated
(brake delay is on).
The state of Logic-5 logical function (mapped to DO 5)
The state of Logic-6 logical function (mapped to DO 6)
The state of Logic-7 logical function (mapped to DO 7)
The state of Logic-8 logical function (mapped to DO 8)
The same as 0xD8 bit 10 (SCR 1 and 2)
