Manual Operation; Reg. 0X01 Bit 23 (Sci State) Set To Ok - Deif IMD 100 Series Integration Manual

IMD 100 Integration manual 4189360015 Rev. G
Info
Logical input must be in inactive or Off, AND bit 1 in register 0x51 must be zero in order to
disable NcR0.

9.6 Manual operation

It is possible to control the motor manually using digital inputs 10, 11, and 12 for service purposes.
These inputs are intended to be connected to three switches in the pitch cabinet, and can be used
with practically no regards to the logical state of the IMD. If VLMS are used, it is not possible to pitch
past them in this mode. See section
During manual operation the position is stored by the IMD every time the motor and brake output are
deactivated.
If a "Bus timeout" error is active when the manual operation is activated, the error is reset.
There are two main manual operation modes depending on the configuration of Reg. 0x01 bit 23 (SCI
state):
•
Reg. 0x01 bit 23 (SCI state) set to OK: manual operation depends entirely on the digital inputs 10,
11, and 12. When going out of the mode, the IMD always goes to normal operation state (1).
•
Reg. 0x01 bit 23 (SCI state) set to Not OK: manual operation dependent on both digital inputs 10,
11, and 12 and special commands. When going out of the mode, the IMD always performs a
safety run.

9.6.1 Reg. 0x01 bit 23 (SCI state) set to OK

9.6.1.1 Prerequisites
•
Manual operation must be enabled in the configuration (0x01, bit 30 =1).
•
SCI state for manual operation must be set to OK (0x01, bit 23 =0).
•
Three switches must be connected to Digital inputs 10, 11 and 12 and 24 V DC (see section
on page 47).
•
The IMD must be in one of the states that allow entry to manual operation (have manual operation
as condition to proceed, see
9.6.1.2 Activation
The IMD is brought into manual operation mode by activating DI 12 (high) following by either DI 11 or
DI 10 (rising edge).
9.6.1.3 Operation
While in manual operation mode only activating DI 10 or DI 11 will move the motor (D10: "-" direction,
D11: "+" direction). The configuration parameters for manual operation will be used.
If either RUN or RFE inputs are low, or the SCI, input changes state, the output to the motor will be
disabled.
