Danfoss FCM 375 [72/106] Fcm series

Bit 07, No function/reset

Reset of trip. Bit 07 = "0" means that there is no reset.

Bit 07 = "1" means that a trip is reset. After reset it will

take approx. 1.5 second until the unit is ready. The

status word will indicate the ready state.

Bit 08, Jog 1 OFF/ON:

Activation of pre-programmed speed in parameter 509

(Bus JOG 1). JOG 1 is only possible when Bit 04 = "0"

and bit 00-03 = "1".

Bit 09, Jog 2 OFF/ON:

Activation of pre-programmed speed in parameter 510

(Bus JOG 2). JOG 2 is only possible when Bit 04 = "0"

and Bits 00-03 = "1". If both JOG 1 and JOG 2 are

activated (Bits 08 and 09 = "1"), JOG 1 has the higher

priority, which means that the speed programmed in

parameter 509 will be used.

Bit 10, Data not valid/valid:

Used for telling the FC motor whether the control word

is to be used or ignored. Bit 10 = "0" means that the

control word is ignored. Bit 10 = "1" means that the

control word is used. This function is relevant because

the control word is always contained in the telegram,

regardless of the type of telegram used, i.e. it is pos-

sible to disconnect the control word if it is not to be

used in connection with updating or reading of param-

eters.

Bit 11, No function / slow down, relay 123, digital output

terminal 9:

Used for reducing the speed reference by the value in

parameter 219. Bit 11 = "0" means that there is no

change of the reference. Bit 11 = "1" means that the

reference is reduced. Bit 11 = “1” will also activate relay

123 (provided parameter 323 = “Control word bit 11”)

and set digital out terminal 9 high (provided parameter

340 = “Control word bit 11”).

Bit 12, No function / catchup, relay 123:

Used for increasing the speed reference by the value

of parameter 219. Bit 12 = "0" means that there is no

change of the reference; Bit 12 = "1" means that the

reference is increased. If both slow down and catchup

are activated (Bits 11 and 12 = "1"), slow down has the

higher priority, i.e. the speed reference is reduced. Bit

12 = “1” will also activate relay 123 (provided param-

eter 323 = “Control word bit 12”).

Bits 13, Choice of Setup:

Bit 13 is used for choosing between the two menu Set-

ups in accordance with the following table:

Setup

Bit 13

1 0

This function is only possible if Multi-Setups have been

selected in parameter 004.

NB!

Parameter 507 is used for choosing how

Bit 13 is to be combined (gated) with the

corresponding function on the digital in-

puts.

Bit 15, No function/reversing:

Reversing of the direction of rotation of the motor. Bit

15 = "0" leads to no reversing, Bit 15 = "1" leads to

reversing.

NB!

Unless otherwise mentioned, the control

word bit is combined (gated) with the cor-

responding function on the digital inputs

as a logic "or" function.

Status word (according to Fieldbus Profile stand-

ard)

The status word is used for informing the master (e.g.

a PC) of the condition of a slave (FC motor).
