PROGRAMMING GUIDE

4. PROGRAMMABLE FUNCTIONS
4.1. Multimotor
The Sinus Penta drive provides 3 separate sets of parameters allowing configuring three control algorithms for 3 types
of motors:
• C009 Number of configured motors =2
• C173 Digital input for Motor 2 = MDI6
When MDI6 is open, the parameters relating to Motor 1 are used for the motor control; when MDI6 is closed, the
parameters relating to Motor 2 are used for the motor control (see the MOTOR CONFIGURATION MENU and the
MULTISPEED MENU).
4.2. Voltage/Frequency Pattern
When using the Volt/Freq IFD control algorithm (e.g. C010 = V/F IFD for Motor 1), you can select different types of V/f
patterns (see the V/f Pattern (IFD Only) section in the MOTOR CONFIGURATION MENU).
4.3. Slip Compensation
When using the Volt/Freq IFD control algorithm (e.g. C010 = V/F IFD for Motor 1), you can set the slip compensation
function for a more accurate speed control (see the Slip Compensation (IFD Only) section in the MOTOR
CONFIGURATION MENU).
4.4. Speed Searching
When using the Volt/Freq IFD or VTC VectorTorque control algorithm (e.g. C010 = V/F IFD for Motor 1), you can set the
speed searching function for the motor speed of rotation, which is useful when the drive controls a motor which is
already running (as for motors connected to fans). See the SPEED SEARCHING MENU for more details.
4.5. Controlled Stop in Case of Power Failure (Power Down)
See the POWER DOWN MENU to set a controlled stop in case of power failure.
4.6. DC Braking
When using the Volt/Freq IFD or Vector Torque VTC control algorithm, you can set DC braking at start or at stop. The
DCB Hold function can be set for the Volt/Freq IFD function. See the DC BRAKING MENU for more details.
4.7. Motor Thermal Protection
The Motor Thermal Protection function protects the motor against possible overloads. This function can be obtained via
a PTC acquired in AIN2 analog input—up to 6 PTCs can be series-connected—or it can be a software protection
implemented through an algorithm reproducing the motor thermal image.
See the MOTOR THERMAL PROTECTION MENU for more details.
For more details about using AIN2 input, please refer to the Sinus Penta’s Installation Guide.
