Word 1: Speed reference/limit from FIELDBUS (integer portion)
Word 1 of the memory map details the integer portion of the speed reference (M042) in either IFD, VTC or FOC mode.
bit [15..8] bit [7..0]
Speed reference integer portion
The speed reference from the FIELDBUS is obtained by adding the decimal portion to the integer portion (see Word 2).
This value is included in the global speed reference of the drive (measure M000) along with the other reference sources
if at least one of parameters C143 to C146 is set as 6:FieldBus.
The speed limit from FIELDBUS is significant if parameter C147 is set as 6:FieldBus and the type of reference of the
active motor (parameters C011 / C054 / C097) is set as 2:Torque with Speed Limit.
Word 2: Speed reference/limit from FIELDBUS (decimal portion)
Word 2 details the decimal portion of the speed reference (M043) ONLY IN FOC MODE. The value sent by the Master
to the Sinus Penta as the decimal portion of the speed reference must be multiplied by 100.
In order to send a speed reference of XXX.50rpm, the low byte of the word must contain the value 50
10
or 00110010
2
(0.50
10
x 100 = 50
10
).
Example: M042=210; M043=50 ⇒ speed ref. = 210.50 rpm

Speed reference decimal portion
Word 3: Torque reference/limit from FIELDBUS
The torque reference from the FIELDBUS (M045) is significant if at least one of parameters C143 to C146 is set as
6:FieldBus and if the type of reference of the active motor (parameters C011/C054/C097) is set as 1:Torque or as
2:Torque with Speed Limit, or if the drive is in slave mode from digital input.
The torque limit from the FIELDBUS is significant if parameter C147 is set as 6:FieldBus.
The value sent by the Master to the Sinus Penta as the torque reference/torque limit must be multiplied by 10.
In order to send a torque reference/torque limit of 50%, the word must contain the value 500
10
or 111110100
2
(50%
10
x
10 = 500
10
).
bit [15..8] bit [7..0]
Torque reference/limit
Word 4: PID reference from FIELDBUS
The PID reference (M047) can be sent from the fieldbus if at least one of the parameters C285 to C287 is set as
6:Fieldbus.
The value sent by the Master to the Sinus Penta as the PID reference must be multiplied by 100.
E.g. In order to send a PID reference of 50%, the word must contain the value 5000
10
or 111110100
2
(50%
10
x 100 =
5000
10
).
