Technical Details Electronically-controlled brake unit for three-phase synchronous motors;.2 up to 7.5 kw (at 4 V/3 AC). Features Brake for preset time Automatic braking current control (effective value) Braking time and braking current can be set Adjustable safety times Monitoring heat sink temperature No-load switching of brake Approvals Electrical data Supply voltage AC: 2... 24, 35... 45, 39... 46, 47... 55, 5... 6 V Tolerance 9... % Power consumption Max. 4 W Switching capability in accordance AC: 25 V/.... 5 A/25 VA with EN 6947-4-, /9 DC: 24 V/.... 5 A/2 W Contact material AgCdO Contact fuse protection 6 A quick or 4 A slow Fuse protection of main current circuit 25 A/68 A 2 s for 5 A version 5 A/7 A 2 s for 3 A version Features Braking current 5 A (up to 45 V AC with internal brake ) 3 A Setting ranges for braking current.2... 5 A effective or,5... 3 A effective Safety times adjustable t V = 24 ms ( 2 ms to 5. s ) t V2, t V3, t V4 = 4 ms ( ms to 5. s) Braking time (monitoring time) up to 945 s, can be set to infinity Remote control connection 47 kw potentiometer for ext. remote control set point 47 kw potentiometer for ext. braking time set value Manually operated braking process via start contact to terminals 6/7 Pulse duty cycle 5 A version: :7 at t brake = s 3 A version: : at t brake = s Environmental data Ambient temperature -... +55 C Storage temperature -4... +85 C Mechanical data Max. cable cross section 2 x.5 mm 2 or x 2.5 mm 2 of external conductor Single-core or multi-core with crimp connector Dimensions (H x W x D) 87 x 9 x 45 mm Weight 9 g Description Logic control with micro-controller Braking current power semiconductor Integrated brake for devices up to 5 A/45 V AC Settings via keyboard LCD display Remote control option for - braking time - braking current - manually operated braking Non-volatile parameter memory Evaluation option for motor temperature sensor (PTC resistor) 9 mm housing, DIN-rail mounting Pulse duty cycle The following are decisive factors when choosing the Motor nominal current I N (I N x 2 = max. braking current I B ) and pulse duty cycle T V t B T V = ----- (T B 25 C/ % I B ) t P The 3 A version can be used to brake larger motors. The ratio of the motor nominal current to the braking current and can no longer be set to : 2. This will result in a reduced braking effect. When setting the braking time (t B ) ensure that the pulse duty cycle for the unit is not exceeded.
