354 [Anlg Out1 Scale]
Vector v3
355 [Anlg Out2 Scale]
Vector v3
Sets the high value for the range of analog out scale.
Entering 0.0 will disable this scale and max scale will be
used. Example: If [Analog Out Sel] = "Commanded Trq,"
a value of 150 = 150% scale in place of the default
800%.
Example
Analog Output 1 set for 0-10V DC at 0-100% Commanded Torque.
Setup
• [Analog Out1 Sel], parameter 342 = 14 "Commanded Torque"
• [Analog Out1 Hi], parameter 343 = 10.000 Volts
• [Analog Out1 Lo], parameter 344 = 0.000 Volts
• [Anlg Out1 Scale], parameter 354 = 100.0
If [Analog Out1 Lo] = –10.000 Volts the output will be –10.0 to +10.0V DC for
–100% to +100% Commanded Torque.
If [Anlg Out1 Scale] = 0.0, the default scaling listed in [Analog Out1 Sel] will be
used. This would be 0-1.25V DC for 0-100% Torque or 0-800% for 0-10V DC.
Scale Block Analog Output
Selects scaled analog output relative to the Scale Block value. Values not in the
[Analog OutX Sel] parameter list can be used to drive the analog outputs. When
using the Scale Block select, the Scale block Out Hi and Out Lo parameters are
not used.

Example
Analog Output 2 set for 0-10V DC for Heat Sink Temp 0-100 Degrees C. using
Scale Block 1.
Setup
• Link [Scale1 In Value], parameter 476 to [Testpoint 1 Data], param. 235
• [Testpoint 1 Sel], parameter 234 = 2 "Heat Sink Temp"
• [Analog Out2 Sel], parameter 345 = 20 "Scale Block 1"
• [Analog Out2 Hi], parameter 346 = 10.000 Volts
• [Analog Out2 Lo], parameter 347 = 0.000 Volts
• [Scale1 In Hi], parameter 477 = 100
• [Scale1 In Lo], parameter 478 = 0
