Motor Thermal Overload Protection; Emc Compliant Installation; Optional Brake Resistor - SODECA VSD1/A-RFM-0.5 Manual De Instalación Y Operación

4.9. Motor Thermal overload Protection

4.9.1. Internal Thermal Overload Protection
The drive has an in-built motor thermal overload function; this is in the form of an "I.t-trP" trip after delivering >100% of the value set in P-08
for a sustained period of time (e.g. 150% for 60 seconds).
4.9.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:-

EMC Compliant Installation

Category Supply Cable Type
C1 Shielded
6
C2 Shielded
C3 Unshielded
1/ A screened (shielded) cable suitable for fixed installation with the relevant mains voltage in use. Braided or twisted type screened cable
where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of a standard cable
within a suitable steel or copper tube is also acceptable.
2/ A cable suitable for fixed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable within a
suitable steel or copper tube is also acceptable.
3/ A cable suitable for fixed installation with relevant mains voltage. A shielded type cable is not necessary.
4/ A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.
5/ The cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body through the largest
possible surface area. Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control
panel using a suitable EMC clamp or gland, as close to the drive as possible. For IP66 drives, connect the motor cable screen to the internal
ground clamp.
6/ Compliance with category C1 conducted emissions only is achieved. For compliance with category C1 radiated emissions, additional
measures may be required, contact your Sales Partner for further assistance.
7/ Permissible cable length with additional external EMC filter

Optional Brake Resistor

VSD Frame Size 2 and above units have a built in Brake Transistor. This allows an external resistor to be connected to the drive to provide
improved braking torque in applications that require this.
The brake resistor should be connected to the "+" and "BR" terminals as shown.
The voltage level at these terminals may exceed 800VDC
Stored charge may be present after disconnecting the mains power
Allow a minimum of 5 minutes discharge after power off before attempting any connection to these terminals
Suitable resistors and guidance on selection can be obtained from your Sodeca Sales Partner.
