+#####SAFETY CHECKS EXPLAINED#####
+#There are two safety checks built-in: one is based on load and the other is based on current. 
+#Current: if Protection_Current > Present_Current we wait Over_Current_Protection_Time (expressed in ms) and set Torque_Enable to 0
+#Load: if Max_Torque_Limit*Overload_Torque (expressed as a percentage) > Present_Load, we wait Protection_Time (expressed in ms 
+#and set Max_Torque_Limit to Protective_Torque)
+#Though we can specify Min-Max_Angle_Limit, Max_Temperature_Limit, Min-Max_Voltage_Limit, no safety checks are implemented for these values
